Really enjoyed my stay and would certainly recommend it to anyone.
=> excellent location: right in front of U-Bahn station
=> neighbourhood: (1) everything you need in the immediate vicinity (supermarkets, restaurants, pubs, coffee shops) (2) Schöneberg has a lot to offer and the other districts are easy to reach
=> very easy and convenient check-in and check-out (was even able to check-in two hours in advance)
=> room was not very big but they really paid attention to detail which made the stay very comfortable (tv with chromecast, fast internet, nice and clean bathroom, number of free drinks, good sound proofing, airco)
