Sorry for not speaking german, only french and poor english....*
Very good address ! Externally, It seems a little bit old and dirty at arival and far away from city center but indeed not; It was very large appartments and very clean and quiet also. Possibility having large or small car park on demand in the underground or above. Very good staff at reception especially the one who speak fine french and explain for you town, bus and so... A bus is direct to center until 20 h 30, after, you'll have to use underground to Berliner tor and after night bus (ask receptionist to fine it because a little hard to find after U station direct to hotel).
