Supposedly a very nice hotel - over the last 5 years I have stayed at about 200 nights in various Sheraton, Westins, about 200 in Marriotts and about 30 in Hilton and Hyatt hotels worldwide, and each one of them has me better than the IC Vienna. Was just so OK, room small, old, window lets through some noise, small bathroom. Stop ok but I would have just given 3 stars, in each Crown plaza (same chain) I liked it better.
