 The rooms need to be better equipped for a 4 star their rooms were very average firstly all rooms have two single beds joined to make a double bed which isnt done quite well So for couples its not a very good choice The washrooms need better toiletries in a 4 star in vienna you would expect more 
 We stayed here for 3 nights the location of the hotel is excellent it allows you to walk through the city quite easily The breakfast is good and the front desk is helpful
