I stayed in Nassa's studio with my 8 year old daughter for a few nights. We had an excellent stay and the apartment was perfect for us. It is also a nice neighbourhood with good local restaurants and very close to public transport with links to tram, underground and train. The trip from the airport was very easy. Just one direct train. Nassa was a great host and very helpful and easy to communicate with. I'd stay here again if we come back to Berlin.
