Located in the 7th district in close proximity to the city center.
Best surrounding available in Vienna (nice bistros and bars), clubs, pubs everything from Maria Hilfer Straße, Gumpendorfer Straße, 1st district.
Fantastic breakfast, nice staff only drawbacks are:
some rooms are smaller than others, ask for rooms ending with 6,8,10 (towards the inner part of the hotel for outside part take 7,9,11).
Fitness area is really tiny but they have good cardio equipment (e.g. waterrower)...
