Great flat and incredible location. Minutes away from plenty of good bars, cafes and restaurants - also a supermarket close by. The bathroom is on the small side and we ran out of hot water once (we were there for a week) - but the kitchen is large and well equipped, he left lots of food and basics in the cupboard for us. The bedroom is huge and the bed was really comfortable. He was also very flexible and relaxed about our arrival/departure times which made things easy. Would definitely stay there on our next trip to Berlin.
