 I booked a superior single room but I got a room with two separate beds which puzzled me a bit And there were no slippers in my room although they were mentioned in the room details Also I think the price for the breakfast is unreasonably high but the service and staff in the breakfast area were very helpful and efficient so I have nothing to complain about in that respect 
 The location is perfect it is very easy to get to the major attractions on foot Just a couple of minutes from the University of Vienna which was my destination for this trip
