Andreas has been extremely helpful and reactive, very easy for the check-in and check-out time. We had a nice welcome with chocolates and cake and that was a very kind attention. The apartment is huge with 3 bedrooms, a leaving room, a studio which can be used as a dining room, a well equipped kitchen and a modern bathroom (good pressure / hot water). Maybe not as cleaned as we would have liked but Andreas has been kind enough to fix this after we called him. The area is very nice if you go on Golzstrasse for instance. U-Bahn and S-Bahn stations both at less than 10 minutes walk. Perfect spot to discover Berlin.
