I really enjoyed Peter's place, and I would recommend it to singles or couples looking to explore Berlin from a cosy and comfortable base. Location is good and in walking distance of Ubahn and bus or tram stations.
I liked the look and the style of the apartment and appreciated its quietness, being located far from the street in a nice interior courtyard.
The booking and communication were smooth and I had no trouble extending my stay as needed. The internet worked just fine and all the little amenities were available.
