Walking to this hostel from across the Zocola and checking in was a huge relief for us. It truly is…read morelocated RIGHT BEHIND the Cathedral. We had just arrived in Mexico City and were a little culture shocked by the immensity of the city, and as ignorant Americans who speak little to no Spanish, it was nice to check in to a friendly, clean hostel with English speakers to get grounded before exploring the city. If staying in the D.F. this hostel is very centrally located. We did take the metro throughout the day and this place is located close to two metro stops.
There is always a bilingual (English and Spanish speaking, I think) staff member at the front desk at all hours to answer any questions. Several times we asked for directions or about taking a bus or metro and were given great advice.
The hostel is super clean and friendly. Our shared room was small, but brightly painted and clean. We did have a locker in the room and we travel with our own lock, so we felt safe locking our valuables up when out of the room. If you don't travel with your own lock, locks can be purchased at the front desk.
At 2:00 PM, which is check in time, there was a long line of backpackers and travelers trying to get a room and a lot of them were turned down due to no vacancy, so definitely make your reservations online before coming, especially if you're planning to stay on a weekend. We made ours on Hostel World and had no issues with the reservations.
There is a bar upstairs and free WiFi throughout the entire hostel, as well as a restaurant downstairs. The restaurant downstairs does serve really good food, and while it is more pricey than other places, it's convenient to grab a snack or drink. The free breakfast provided upstairs was fresh and hearty with lots of fruit. There is free coffee provided, but it's the instant kind. Another huge plus to this hostel was the free filtered water which is available on every floor in a drinking fountain. We refilled all of our water bottles and didn't have to buy any water while in Mexico City. The water fountains on the bottommost floors have the coldest water.
There were some loud, obnoxious juveniles in the hostel, so if you want to get a good night's sleep definitely bring ear plugs, as a lot of the rooms open up to the restaurant and lobby downstairs and voices travel far in this hostel. The showers and bathrooms were clean and we were even provided with towels and soap, which is a plus for hostels. The same people who run this hostel also have others throughout Mexico, so it looks like a nice, trusty chain of hostels to me.
