 Nothing 
 The quality and professionalism of this hotel were exemplary There was a happy friendly atmosphere and it was not pretentious WiFi worked well in the room beds were very comfortable the room temperature was easily controlled and the breakfasts were to die for The stop for the No 2 tram Strassenbahn was only a couple of hundred metres away The tram service was frequent and the No 2 takes you to many places of interest and connects easily with U Bahn and S Bahn train services
