Norbert's apartment is very cool with some amazing decorative touches. It has all you need for a stay in Berlin. It is located in a very nice area that is easy to reach from the airport and the rest of Berlin by public transport and on foot. Although Norbert was away when we arrived, his friend was there to greet us and answer any questions. When I return to Berlin (as I think anyone would once they visit) I'll definitely stay in Norbert's again.
