It was really easy communicating with Alan and Kasia, they replied fast to emails and sent us very helpful and comprehensive info about the flat and about things to do in Berlin. We used your guide lots, thanks! The flat is lovely, very clean and had everything we needed including (joy) a very comfortable bed. Prenzlauer Berg was a great spot for us to have as our base, very interesting and relaxed area, lovely places to explore, good food, and super close to the centre of the city. Also very easy for Tegel airport. One of the best things about the flat is the proximity to public transport, just a couple of minutes from train and tram. I feel the cold and it was -4 one night when we were there, the flat warmed up fast and there was very welcome extra bedding. Plus blinds which meant we got plenty of rest which we needed. We had a wonderful time and wouldn't hesitate to recommend it. Thank you very much for the lovely stay Kasia and Alan.
