What can I say about this hotel that has not already been said?
I stayed here because of all the great reviews and I agree with everything. Stay on the executive floor - call Hilton reservation direct as they gave me a fabulous rate - cheaper than on the internet.
Although you pay more for the executive floors - you get so much more. Visit the lounge on the 12th floor. We went for afternoon tea and cakes at 3pm and they were offering champagne, wine and a full bar - all included in the price. We went back for a drink before we went out and they had put out the most wonderful canapes and the bar was still there. You can take as much as you like! Breakfast was included and was in the same lounge and it was plentiful and there was lots of choice.
The lounge has fantastic views across the stadpark and I sat there for some time whilst my husband had a massage in his room (not included in the price but it was well worth the money).
The staff here are among some of the friendliest we have met on our travels and we cannot rate this hotel enough!
The beds were very comfortable and the decor was modern and delightful.
It is ideally located and only took a few minutes walk to get to St Stephans cathedral, but it is also very easy to walk around the whole of vienna and walk back through the park to the hotel.

The hotel was very nice. The front desk and concierge (when available) were great. However, the lobby bar was very under-staffed for a Friday night. The next morning, they seemed to be under-staffed at breakfast as well. The restaurant was bustling and they almost seemed offended when my colleagues asked for coffee. When you're paying €24 for a buffet, they'd better have some decent service. The next morning, breakfast was not crowded at all and it took even longer to get coffee. The first time, we asked the gentleman and he grabbed the coffee and filled up two other tables first, then to ours. Towards the end of breakfast we asked for refills and what does he do? He disappears for 4 minutes, only to reappear bussing a table within view. When he saw my perplexion, he offered no apology or even kind attitude. Instead he remained pointed and unprofessional.

visited this hotel in the middle of oct 05 and stayed for 3 nights in an executive room on the executive floor, the hotel was really not upto what i was expecting after reading some reviews on this site.
On arrival at the door, the doorman removed our bags from the taxi and just vanished after that and kept us waiting for the bell boy, had to then go and call someone from inside to take my bags in.
the guy who checked me in on the executive floor was acting as if he is doing me a favour,the room they alloted to me was really noisy as there was work going on in the park opp to the hotel.the airconditioning in the room was not working and it took me one whole day to get someone to check it, and after the mechanic pronounced that it cant b e rectified, and after so many complains after that the manage of the executive floor did come to meet me but told me she could do nothing as she did not have any alternate room available.She just could not do anything else for me and this was astonishing coming from a manager of an american chain hotel, where they really know how to rectify things for their clients specially regular clients.
the club lounge for all the 3 days that i was there had the same repeat the same pastries and snacks for their guests
all in all a bad hotel ,and the hotel concierge down at the lobby level was extremely impatient and showed it all the way, very bad hotel, would not recommend it to anyone unless and until the hotel gives some tips to their employees on how to behave with their guests.very disappointed

I've saved Hilton points for a long time and cashed them in for a five-night stay in Vienna. It was a good use of points, since the hotel is not inexpensive.
The hotel is across the street from the new express train from the airport. Faster and MUCH less expensive than Heathrow Express. On the return trip, if you're taking Austrian or Lufthansa, you can check in and check you bags at the train station.
A fast, friendly and efficient check-in awaited me. My room had magnificent views of the city. It was maintained beautifully throughout my stay.
For a U.S.-style hotel, it surprisingly has limited smoke-free areas in the hotel. The lobby has a large dining area that I found completely unappealing because of the heavy amount of smoke. So -- I didn't eat there.
In every other respect, the hotel was a wonderful place to locate during a special vacation to Vienna and contributed to the great experience I had being there.
