 I wouldn t have rated this as a four star hotel The bathroom in a twin bedroon was all glass which was a bit awkward between friends The nearest station Pratastern felt unsafe to walk back from at night as a female as there are constant congregations of groups of men drinking alcohol outside of it My friend was followed by a drunk man whilst walking back alone in the afternoon who only stopped when she walked into a nearby hotel to ask for help 
 Good hotel Clean rooms and the reception staff were friendly and very helpful Easy and quick to get into the centre of Vienna
