Jan is a very welcoming and interesting person, we had quite a lot of talks about art, Berlin and evironment. The location is safe, both quiet, as well as full of life and good places to visit at the same time. It was really comfortable to stay at Jan's place and trully felt like staying at a good friend's (a special pleasure - apartment design and lots of art books).
Thank you for such a warm welcome! And highly recommend to stay at Jan's place.
