It was pleasure to stay in Karsten's appartment. It was very nice, as seen on profile photos. It's located on silent street, so there's no noise from it. U-bahn, nice restaurants and grocery store are in walking distance. Free parking on the street nearby.
It was easy to comunicate with Karsten. He gave us information about surroundings, nice places to eat and other things to make our stay very good. Highly recommended host!
