The staff are very nice - no complaints there. But a room service menu with 4 items, nothing vegetarian, nothing really edible in the building was a let down. Given the hotel is in the CBD, instead of closing their main restaurant on Sunday and Monday they should make it available as there is nothing else nearby. Do not be fooled by Donauinseln either, it’s just tourist crap in hot weather with no aircon and sun beating down. I booked for 4 nights and we left after 2 moving to the Hilton, which is closer to real restaurants and cafes, museums, etc, cheaper, and nicer. We gave them the room back 2 days early and asked if they could please reimburse the 4th night given they had no food we could eat but they refused. They did let us off on mini bar items, which was nice but I would have preferred something for dinner rather than Pringles and sparkling water. In addition, the carpet in the room was old and filthy. It used to be close to shag and now matted down and dirty. Oh and there is no way to watch the TV - from the bed or the couch! And of course no movies or content worth watching!
