We stayed 5 nights and really enjoyed this very spacious studio. Charlotte was fantastic with her advice and prompt reply to several questions we asked. The apartment is decorated with lots of art and she has included all sorts of aids for the traveller. It is on the ground floor of a block of units but has its own private entrance. The area is lovely with scores of restaurants nearby. It is probably not as Central to everything as we would have liked but once again Berlin is not a particularly centralised city. Taxis here expensive and the subway is about 10 mins walk. We didn't use the buses so they were probably a better option. Overall a wonderful stay and we would recommend.
