 Our room had an interconnecting door with the room next room Unfortunately there was no sound proofing whatsoever Other hotels I have stayed in have had a double door which has acted to muffle the sound We could hear absolutely everything that was said and done by our neighbours This was irritating early in the evening but unacceptable particularly on the last night when a couple with a young child arrived late and seemed reluctant to go to bed 
 Location was terrific Very close to the centre of Vienna and all the major visitor sites The room was very well appointed and the bed extremely comfortable I was impressed with the choice of pillows The breakfast was excellent and offered a very wide choice of extremely tasty food
