Patrick is an exceptionally nice guy -- really takes time to look after his guests. My family (including three small children) had a great experience. The flat is nicely organized with plenty of sleeping space and a big open kitchen. It is on the ground floor, but the street is quiet and security is not an issue. Clean and very well maintained. For visitors looking for a quiet spot in Berlin that is also close to the center and well connected to "happening" neighborhoods, the location is hard to beat. 10 mins walk to Akazienstr -- one of Schoeneberg's nicest areas -- it is also a quick 2 blocks to the S-Bahn and 10 mins ride to the center. Good pick for a Berlin vacation.
