We had a very pleasant experience at Rolf and Veronique's flat. Rolf was out of town, but delightful Veronique gave us great directions and welcomed us warmly, taking time to orient us to transportation possibilities and city sights. The flat was just what we needed: clean and quiet (faces an inner courtyard) and a good base for touring the city (not too far to an U-Bahn station). Thank you!
