The flat is beautiful, very comfortable and in a very quiet and green zone of Berlin. The zone, and the flat itself, is very well served by public transports but it's not very close to the city center. We decided to rent 4 bikes and we explored the whole city moving from the flat, but we were trained to do it: from the flat to the center it takes something close to 40-50 minutes cycling. However I consider this choice a very good one.
