Carola's home, including the room reserved for guests, is very pleasant and beautiful, while also providing good comfort. The home also has a beautiful garden. It is located on a quiet street, in a nice neighbourhood. Getting to and from the city center (or other parts of Berlin) is easy and convenient, by train or bus.
The communication with Carola was straightforward and she was very helpful with info when we needed to go see a doctor in Berlin.
We highly recommend staying at Carola's place, especially if you have an interest in (contemporary) art and/or are looking for a very pleasent place with character (as opposed to a standard apartment or hotel room).
