Alan & Kasia are very responsive and easy to communicate with. The check-in process was easy and the company they employ was very accommodating. The flat is spacious and plenty of room for 2 people. It is on street level; however street traffic (pedestrian and vehicle) was negligible. Conveniently-located - 1/2 block walk to M4 Tram and S-bahn. Easy walk to heart of Prenzlauer Berg.
