If anything the apartment is even bigger and nicer than the pictures show. The front room and bedrooms are huge and the decor is gorgeous. V was very accommodating, allowing us to pick up the keys later in the evening and made us feel very welcome with a quick tour of the apartment.
The neighbourhood was perfect for our requirements. Close enough to be in Kreuzberg within 10 minutes in a cab or on the S Bahn, but also nice and quiet. We had great mexican style breakfast in the cafe next door.
I would definitely recommend the apartment and would love to stay there again, next time I'm in berlin.
