We, a family of 4 had a very good stay in Kreuzberg. The flat is in a gated community, but hip. So the children are able to go outside to the community playground without crossing a road and are safe. The flat was almost perfectly clean, had a good feel to it, a great tree in front of the window and was quiet . I don't recommend it for small children because of the stairs. Kontakt and communication with Gregor was pleasant.
