Marcel was extremely helpful before and during our stay. We had great communication with him beforehand and he recommended some great places to see and eat at in Berlin. The apartment is in the hip area of Kreuzberg and also very close to the U Bahn which was helpful in getting around Berlin. It was a extremely clean and comfortable stay and we felt right at home! p.s. the stairs are a bit of a killer but it helps burn off all the amazing food you will eat in Berlin ;)
