Overall a great stay at the Doubletree hotel. Convenient for the Schonbrunn Palace and underground station, approx. 20min walk. Hotel staff were very friendly and helpful with all our queries.
The breakfast was very filling and such a choice. We enjoyed the bar food, and although not advertised this was also available as room service.
My only criticism would be with the steam room, it wasn't working when we arrived and 6days later still not available despite our questions on it's return to service.
Overall well worth another visit.
