We had a wonderful stay in Kreuzberg. The apartment was clean, funky and very well fitted out. All information was clear and we felt very secure that our hosts were contactable should we need them. There was a very helpful information pack in the apartment and the Berlin guide book was well used by us. We loved the area - it really did give a feel for the real Berlin and if we returned we'd definitely stay in this area again.
Our kids loved the science spectrum centre at the tecknik museum and the static hot air ballon at checkpoint Charlie.
The only thing I think could be improved is if it was made clear that although the kitchen and bathroom are separate, the bedroom and living room are not divided by a door which meant we couldn't watch TV in the evening because it would have woken the children. As it happens it didn't bother us as we were happy to read and go to bed early and the beds were all very comfortable so we all slept really well. Thanks for a great stay.
