Whether it was with a restaurant reservation, or a newspaper, or insights on where & how to get around their Hauptstadt of Berlin. They excelled at service. Also, their prime location, next to the U-Bahn Potsdamer station, makes it a key jumping off point for whatever/where-ever you want to go and do.... Charlottenburg, Kaufhaus (KaDeWa), the Eastern Gallery, or even the Brandenburger Berlin Flughafen are all within a convenient U-Bahn ride from here.

We walked to most of the attractions since the weather was so beautiful. The room was very well appointed, modern, and clean. The shower featured water jets from the wall and was very nice. I was pleased to find an iron and ironing board in the closet. Be warned if you ask for a double bed: You'll be given two twin beds pushed together. I kept thinking to myself the London Underground warning of "Mind the gap!" because of a nearly catastrophic 3am separation of the beds, which roll away from each other quite easily. The spa is very small but there were only six loungers and guests were grabbing for them. The pool was quite cold. There are also saunas and an exercise studio, all of which looked well kept. You will be sorry you paid €16 each for the breakfast buffet. It was included in our room fee. The food was of average quality, but there wasn't a large selection to choose from and there were no chefs making omelettes or waffles. Also, the good tables by the windows were reserved for guests staying in the premium rooms. I'm never a fan of a hotel creating a class system amongst their guests. The bar was okay. Not much action there at night. My only complaint was that housekeeping never refilled the coffee in our room on all three nights but the front desk was responsive when we called to complain. I question how many stars this hotel has been awarded. It's advertised as five stars by various online booking sites, but they are not displaying their rating anywhere nor is it mentioned on the hotel's website. I feel it's lacking some critical ingredients to make a five star rating, like no bellhop, concierge, newspapers, or laundry service, our lunch and dinner offered in the restaurant. All in all, I still highly recommend this hotel for tourists who want a great hotel with easy access to the train network.

Terrible wifi connection, terrible check-in process, key didn't work consistently, restaurant didn't have basic menu items, 6 people at the front desk and only 2 were actually working, service staff consistently failed to service the room during a 9 hour periods when I was at work, and then wanted to service at 8am on check-out day. But most of all the attitude of the employees was off putting. Paying customers in a hotel shouldn't feel like their very presence is a burden. Do better for your future customers. I will not be one of them.

I also got a "bid what you want" upgrade to a room on a high floor overlooking the street. The layout for the 2nd tier room is small but perfectly functional for a single traveler or couple, and I loved the thoughtful touches like a small chair in the bathroom, umbrella in the room with a holder, and hooks on the wall near the closet. The (nonalcoholic) drink minibar is free to take from and refilled daily which is another plus! And they had small chocolates that were refilled daily as well. I didn't partake in any breakfast or other food, but it did look good when I passed by. The garden area outside is nice to relax or work in. The hotel itself is on a quieter street but near many different modes of public transit - tram, bus, subway. The front desk warned me about needing coins for the tram / bus and was happy to exchange some bills into coins for me every morning as well. Not many taxis passing by but the front desk will call one for you very quickly if you ask. There are also bikes and scooters you can borrow. Overall I had a great stay and would have loved to stay longer! I had to move to another hotel for work, but wish I could have stayed at the i31.

Cons: - not the most sexy of neighborhoods, although so central and a ton of highly rated restaurants and cafes nearby. - street itself is quite ugly. - bed wasn't the comfiest unless you like really hard beds. Side note: the beds weren't awful, just super hard and I'm a plush kind of gal. - breakfast looked magnificent, but was quite pricy at 16 €. If you can find a deal and in Berlin for a short time, looking to be near the train station, this is a no brainer.

It's best feature is its location - it is proximal to many shops, restaurants, and most importantly, the train station. You can get virtually anywhere quickly due to this hub-like location. My reception experience was pleasant as the employees took their time to ensure I had everything I would need and made me aware of every amenity that I could take advantage of. The room I stayed in was single suite that was freshly made and cleaned thoroughly. The personal air conditioning was also a very welcome feature of the room. I also experienced their breakfast buffet which was a step above a typical continental breakfast. Their omelet station is a great addition along with their multiple coffee machines. If you value personal security, rooms can only be accessed with your hotel card and you can only access floors you have reservations to. There is also a separate lift for pool access. Overall, would stay here again!

The breakfast, praised by others, is indeed quite good and varied (with British and American breakfast dishes, not just those ham sandwiches the Germans like because they know no better); especially good are the scrambled eggs, which, mixed with sausage and spinach, are that rarest of things: scrambled eggs left out in a heated salver that were not perfectly vile. But be warned: the staff will leave a shot-glass full of what looks like orange-juice at your place. It is not: it is wee litte joke: a powerful spiced waker-up potion which has roughly the impact of eating a tea-spoon of Wasabi. And--in the nicest possible way--the staff chortle at your reaction.

Ubers are all over the city and they arrive FAST! The hotel has a gigantic glowing red sign at the top of the hotel so that if you are walking, you can spot it quickly. This hotel is located in what was East Berlin. It is a lovely hotel. There is a lovely grand staircase on the first floor. If you arrive and realize you forgot your power adapter, the hotel will allow you to use one while you are there. They will charge you 20 euros for the use and will remove the charge once you return the adapter. We book our hotels through Marriott.com and use the default settings, we were told that we need to pay extra for the second guest, we said no problem. Elevators: there are 3 running elevators. Room: on checks-in we asked if there were any room upgrades. We got a junior suite (Room 572). A keycard is required to make the elevator move. Room 572 is far from the center of the hotel. Your walk down a long corridor so I was thrilled it is far from the elevators. It is a nice spacious room with sitting area opposite the bedroom. The room runs hot, so we turned off the furnaces and then opened the windows to cool the room down. Even with the furnace off, the room was warm. There is a nice no brand Nespresso machine with pods. There is a mini fridge where you can purchase drinks to consume in your room. Bathroom: very spacious and well lit bathroom that made easy to apply makeup with plenty of counter space. The mirror is the right height for me at 5'8" tall. There is a standing shower. Nice amenities: shampoo, conditioner, body lotion. Living room: nice size TV, desk area with one plug with USB-C and USB connector. There are plenty of European plugs for charging. Couch for watching TV, 2 ottoman style seating for putting on your shoes, and a table for eating snacks. Bedroom: King size bed with nightstands on each side. The night stands have European plugs with 2 USB connectors for charging devices. Smaller TV and tiny when considering distance to the bed for watching TV. Gym: there is a small gym onsite with a sauna. The gym is located in an odd area. We were told go to room 513 and take the elevator down to the gym. Sure enough go to room 513 and there is a tiny elevator. Take it down and you come to a lobby area. The sauna is off to the right but the door was locked the entire time we were here. Then you go around the corner to a series of doors. Open the one directly in front of you and it opens to an awkward open area. It looks like a pool should have been built there. But there are seating places to the right and left and the incense is quite strong, maybe a meditation area? There is a workout area to the left with treadmill and stuff and a water station. Sleep Quality: during the day we could hear noises from other rooms and ambulances screaming by on the street below. At night we could hear people stomping above us but when it came to sleeping time, the noises stopped. The sleep quality was very good but the hotel felt empty for most of the days we were here. During the summer months, it might be a different story. Breakfast: included with our room since we are Marriott Elite. We ate there everyday for our trip and our last day, the young girl was your reservation is only 1 person. We said no, we paid at check-in and 2 should be included for breakfast. After quite is discussion, she was quiet and happy after checking. The breakfast buffet is very nice and highly recommend. There is a nice omelet station. NOTE: There are two Rewe grocery stores within walking distance of the hotel. The first one has a better beer selection. The second is within a bigger mall building and has a better bakery than the first Rewe. Bring your own bags or purchase has expensive reusable Rewe bag.

Overall a full service, clean hotel in a good location…read more Arrival: Arrived by Uber from the main train station. No doormen upon arrival. Check in: Fairly efficient check in process. Asked for a free room upgrade based on my Marriott/Westin status and the clerk upgraded us to a junior suite. Room Junior Suite 572: A large, comfortable room, huge by European standards. The suite included a large living room and a separate bedroom with king bed. Both the living room and bedroom had smallish Samsung TVs (small by U.S. standards). Nice coffee maker and mini refrigerator. Bathroom: Decent bathroom with good counter space and great lighting. Downside is no tub- shower only. Water pressure was adequate. Mediocre but functional hair dryer. Bed: King sized bed with decent linens. We had to remove the heavy liner from the duvet because the room was on the warm side. Sleep quality: Better than average, but some street noise made its way through the windows. Housekeeping: Unless you're proactive in asking, the housekeeping is below average. For example, we had no facial tissues for 2 days. Once we left a note and a tip, the facial tissue was restocked. Sometimes complimentary water was restocked, some days not. Breakfast restaurant: Based on our Marriott status, we received a nice complimentary breakfasts. Service at the breakfast restaurant is pathetic, but the food was good. We consistently were not served coffee. So we simply grabbed coffee urns each morning. Staff for some reason only offered coffee and any level of service to older Germans. Anyone foreign or young the staff ignored. Overall service: Between reluctant and non-existent. That's Germany for you. Don't expect helpful staff. Gym: Small but functional gym with standard exercise equipment like treadmills, weights, etc. Power outlets: Be sure to bring adapters for German outlets. The room had no U.S.-type power outlets. Misc: (1) On our last day, we found a silverfish in the bathroom. Also, this hotel allows pets. We consistently heard dogs barking on rooms. (2) There's a Rewe grocery store about 5 blocks away from the hotel. Bring reusable grocery bags to haul your purchases back to the hotel. (3) We were skeptical but tried a Kebab restaurant nearby. Wow! The Donor kebaps are great! Try Mr. Kebab 4 blocks away.
