TL/DR: Good economic choice for Oktoberfest. I'd look elsewhere otherwise. WiFi is painfully slow,…read morebreakfast is overpriced.
So this hotel has your typical European small rooms and beds. The front desk staff all speak English well and are very helpful and friendly. The cleaning staff don't really knock and tend to just come in the room. If you sleep in, be prepared to yell out "später, bitte!" (Later, please) under your covers while recovering from an Oktoberfest hangover.
In terms of location - this hotel is located on the last stop of the U5 line. For Oktoberfest, that's pretty good as you get a direct line to Oktoberfest without having to change trains. Plus, being first to get on, you're guaranteed a seat (although there are a lot of stops). There's also an Aldi for basic shopping needs, a bank with an ATM and an Italian and Asian restaurant. (Didn't try the Italian - but the Asian quality was "meh". A good option if you're just looking for convenience over quality).
The Wi-Fi is technically free but painfully slow. Everything takes a while to load, you constantly get kicked off and have to log back in. If you're trying to plan out what you're doing for the day, you have to spend a good 30 minutes because everything is so slow. Forget about youtube or pandora, the internet is too slow for streaming. They also limit you to a single device (although you can up the limit to 3 for 10 euros a night). This was by far the biggest disappointment.
Finally the breakfast was okay - scrambled eggs, bacon, toast, ham, sausage, cheese, yogurt, fruit and a few other things served buffet style with bottomless coffee. However - for 24 euros a night, I would say far too expensive (maybe that's just Oktoberfest prices). You're best just grabbing something to go from the U-bahn station or one of the cafes in the local area.
It's a little hard to judge this hotel as I would ordinarily consider what I paid to be too much for what I got, except that it's Oktoberfest and every hotel charges insanely high prices. Because of this, I opted for a 3 star over a 2 star. If they get the Wi-Fi up to speed, I would come back for Oktoberfest. But overall - I say look elsewhere.
