We spent in Berlin seven days. It was easy to be contact with David. It was very easy to come in and then in the end leave the flat. We liked the situation very much. We spent our days in museums and that kind of places. In the evening it was easy to come to the flat and have dinner nearby. There were pleasant cafes and places to eat. There was enough room for two person. The bathroom was just perfect. All in all we had very good holiday in Berlin and the flat was important part of it.
