I stayed several times in this hotel on my business trips. All rooms were very spacy with large windows, comfortable bathrooms, flat-screens, minibar, etc. Rooms in higher standard also have coffee machines and in the bathroom there are both walk-in shower and a bathtub. There is free, fast wi-fi with no password in the entire hotel
The location is great for both sightseeing and business (very close to Belvedere).
The price for the room is reasonably low for Wien, but the breakfast is a little bit too expensive (over 20EUR).
What I didn't like is quite poor fitness room - cardio only. In addition there are no ironing board in rooms and you can’t get one on evening arrival (need to wait until morning).More
