Even though we did not get to meet Suse, the communication with her was smooth and her boyfriend welcomed us, showed us around the apartment and explained everything necessary.
The flat was very warmly furnished, the way you could see soul of Suse everywhere around. We have felt almost like at home.
If you do not mind that the flat is not situated in the very center of Berlin, the metro will take you anywhere in a few minutes.
We had a lovely trip in Berlin and can recommend this flat to anyone!
