The location was excellent, about 2 minutes from the Savignyplatz U-Bahn. I had a small single room, but it was very clean. The TV had more channels that I was used to, and amenities like a mint on pillow on arrival and a nice, powerful shower and soap. The bathroom was in good shape, and the wood floor was nice. I'm not sure if the hotel is new or if the rooms were just recently renovated, but it is very up to date and clean. Breakfast is also big, with a lot of nice options.
A couple small negatives. The staff only speak a small amount of English, but I got by okay with pointing and facial expressions. They are all very nice. It can be noisy at night because of both street noise and noise from the other rooms ... the rooms are close together and it was definitely possible to hear people coming in late at night. No staff is present from 10 on, so you have a key to open the front door and another key to open the door to the hotel, which is up one floor from the ground level.
Overall, I had a very nice stay. Good value and amenities for such a location. Also, I don't think many people know about it yet.
