The apartment is very spacious and on the top floor of a lovely house in a nice leafy part of West Berlin so we had the feeling of staying in our own chalet in the forest. It was spotless! Regina is an entertaining host and her authentic Berliner accent was music to my linguist ears. We had a nice chat and a good laugh with her as I do speak passably decent German. The chateaux of Potsdam are easily reached with bus 638. A great weekend of Gemütlichkeit - thank you Regina!!
