Very impressive hotel. In particular, it is close to city center. Tram station is in front of hotel, 1 min walk max. It takes only 20 min by tram to city center. This is a new district, means less crowded. I am at first floor but never hear any noise from street.
Vienna Central Station is only 7 mins walk from hotel. Supermarket, Spar and Billa is witin 7 mins walk radius. Even if you are tired or want to pick up some late night food, there is a restaurant near the hotel open till midnight, only 2 mins by foot.
The only 2 things I want to comment is,
(1) missing safety box and a fridge, these are basic utilities that all hotels should have.
(2) the air conditioning sometimes drains. It does not affect me though.
