My boyfriend and I truly enjoyed Berlin, and the flat was part of the experience. The apartment is nice and is the same as on the pictures. The location is just brilliant - easily accessible by public transportation if you are lazy or need to go somewhere far from the city center, otherwise, all the main attractions are within walking distance. A crazy lot of shops, cafes, 24x7 shawarma places in the area, but the flat itself is very quiet and relaxing.
Leonardo has been very helpful and friendly. Although we didn't meet in person, all went smoothly.
