When I first arrived at the the apartment I was a bit worried, but the inside of the apartment is much nicer than the outside. The apartment was spotlessly clean and the room was comfy. There was also a large fan which was a god send in the heat wave. The apartment is a 5 minute walk to a U and S Bahn station. Unfortunately I didn't get to meet klaus as he was on holiday but his co-host Christof came to check me and he was very nice and helpful. Great apartment. Thanks a lot klaus.
