We really enjoyed our stay at the apartment. Very clean and well-kept. The owners are very nice people, prompt and helpful. The only issue for us was that the place wasn't so central. We like to visit art museums and found it a little far as we have to change many trains to get there and as everything is in German it was hard to get directions. We had a hard time finding a cab on the morning we left, so plan to call one if you want to take one. We had great sleep as the area surrounding the apartment was very quiet. We love Berlin and we enjoy our stay otherwise.
