Just to add to the recent comments about this hotel, I'm at it right now and agree with the reviews. It's a nice place, and this week's rainy weather in Vienna made it a no-brainer versus the Marriott a few blocks away when coming from the airport. Spotless room, early check-in and beautiful lounge, as detailed by others. The only minor negative (not limited to the Hilton Park) is the extremely slippery shower floor. As hotels transition to the dispensers in the shower, they need to realize that shower gel and a gloss floor are not a good mix. If a coarse surface isn't possible at least some grab bars would be a proactive investment. Otherwise, great hotel in perfect location.
