We stayed at Michael and Kirsten's place for four weeks and had a fantastic time. The apartment is very clean and exactly as described and shown in the pictures. The location is walking distance from the suburban S5 line as well as bus service. It is located in a quiet suburb where you can enjoy comfortable walks or biking but still only 15-20 minutes from city center. We liked the fact that after a long day of sightseeing, we could come home to a quiet neighborhood to relax.
Michael and Kirsten are great hosts - they took care of all our needs promptly and also gave us a lot of advice about sightseeing in Berlin and Germany. In summary, this is a terrific place and a great bargain. We would stay here again in a heartbeat.
