This is a great place to stay: great location within reach of all the main sites, and within walking distance of Kreuzberg's shops, cafes and restaurants. Martin is a great host, with great local knowledge, who was always there to help when needed. The apartment is just as described, clean, with great facilities, and plenty of room for a family of 4 with 2 grown-up children, as we were. Definitely would stay there again, or any of Martin's other places.
