The contact with Bernd and Katja was smooth. The replies came fast and reliable and the information was all very helpful. Thanks a lot again for the good tips. The bike rental was really convenient and well. The apartment is absolutly nice. It was missing anything. It is very comfortable and tastefully furnished and situated great. We were even lucky enough to find a parking space outside the front door. We had wonderful days in Berlin and can only recommend anyone to book this place.
