We were a group of 4 friends and we spent 7 nights in Berlin. We had a great time in the house, it was very conveniently located and just right for our needs. The communication with Dennis was always very easy and he was always on hand to clarify any doubts and help us if we needed it. The cleanliness of the flat was also good and there was plenty of washing up liquid in the house if needed.
Absolutely recommended flat!
