A very nice hotel! Superb service, from absolutely everyone you met from the staff. Nicely decorated. The breakfast was ok, I enjoyed the concept and the experience, but the produce/quality could level up a bit to match the rest. The location is also good, you can walk to most of Vienna, but not in the most touristy area still.
The only downside was the parfyme/refresher they sprayed in the room. SO heavy smell, unpleasant. Also one in our group is sensitive to perfume, this was not good not to be warned when booking and there is no way you can remove a product like that when already sprayed.
Recommend you to request the hotel in advance not to spray this before your arrival, was too much/unpleasant also for the ones not normally sensitive to perfume.
Besides that, everything was highly recommendable!
