Very nice and spacious house in a quiet and charming neighbourhood (except from the occasional trains passing by). The house is actually bigger than it looks in the pictures, and the bathrooms are quite new and luxurious. There is a 10-minute walk to the S-bahn which will take you to all the major stations in the inner city, so the house is a great starting point, for exploring Berlin. I can only recommend staying with Clemens and his family.
