The Do & Co Hotel Vienna is a stunning five-star hotel and is located in the heart of the city center of Vienna, right opposite the St. Stephen’s Cathedral. The Haas Haus building was designed by Pritzker-prize winner Hans Hollein and later completely refurbished to its present incarnation by Hollein himself. A visit to the Do & Co Hotel Vienna is a truly luxurious experience and is an ideal destination for both business and leisure travelers alike.
