Gerhard sounded really thoughtful and considerate beforehand and the reality was just the same. We had a difficult journey (no thanks, Deutsche Bahn) and Gerhard went out of his way to help. And continued to keep in touch throughout the week, without intruding. The flat was perfect - Altbau, clean, tidy, full of character and in a lovely quiet location that was nevertheless close to the heart of the city. We'd like to go again, so danke Gerhard.
