We really enjoyed our stay in Hubert's place. It is in an ideal location for exploring Berlin and is right next to a U-Bahn station. The apartment is spacious, clean and very comfortable and had a good WiFi connection. Collecting the key was easy and there is a lovely restaurant on the ground floor of the apartment block. The apartment is on the 3rd floor and is only accessible by the stairs. We would definitely stay there again and would recommend it to others.
