Susann's place is wonderful. I stayed for more than a month and my stay was perfect. The apartment is beautiful and the neighbouhood as well. It is really well located, very near Treptow Park which is also beautiful. The room is very big and bright, and the bed really confortable.
Susann is not only a great host, but also (and more important for me) a very nice person. She helped me a lot with some issues I had to solve at the end of my stay. Without her help, everything would have been much more difficult. I would definitely come back :)
