This might possibly be, the best rental I've ever had. Matthias is warm and responsive, prompt and detailed. He checked in with us before, during and after our stay and I genuinely got the impression that he thoroughly enjoys being a host. His home is spacious and well appointed, in a great location and felt very comfortable and safe. If we had had more time, I would have enjoyed simply spending time in the apartment and relaxing. This is a true gem, and we will be returning next time we're in Berlin. Thank you Matthias!!
