 The city square adjacent to the hotel was being reconstructed causing difficulties for pedestrians Our taxi from the airport had to drop us at the edge of the construction area so we had to drag our bags through about three city blocks of some extremely tight and crowded sidewalks 
 Expensive but the view of St Stephan cathedral was well worth it Excellent rooftop restaurant and another great view from the 6th floor lounge My wife and I shared a standard room on the third floor and were thrilled by the high quality fixtures and furnishings For our next visit to Vienna we will definitely stay at the DO CO because other hotels would seem ordinary
