We really enjoyed staying at Jan's apartment. It is very spacious, very clean and extremely well equipped. The location is very quiet, even though the apartment is on the ground floor. It is also very near the U-Bahn and so easy to get around. Perhaps the bed in the main bedroom could have been a little bigger, but this is a very minor point. Jan is an excellent host meeting us for the key pick up as well as showing us personally around the apartment and the local area. He was also super-responsive to any questions we had. We thoroughly enjoyed this place and highly recommend it.
