My experience in William's appartment was really good. He is a very nice guy, friendly and receptive. I stayed there for one month and a half and I felt like I was at home. The appartament is clean and very comfortable, with everything that you need. The location is also great, near from a lot of things, supermarkets, shopping mall, a big Park, restaurants and a S Bahn station. You can go to everywhere in a few minutes. And the price is really fair. Perfect place to enjoy this beautiful city!
