We stayed here in 2009 and can recommend Hotel Am Parkring. The location is excellent--about a 10-minute walk from the center (St. Stephen's), across the street from Stadt Park, and convenient to the tram. Because the hotel is on the top floors of a tall building, it is quiet with wonderful views. Our room was modern, spacious, and clean with a nice bathroom with tub. There's no "charm" (like the old hotels), but it's a great place to stay. It also has its own underground parking garage, which we used for the Volvo we'd picked up in Sweden at the beginning of our trip. It stayed there the whole time since everything was within walking distance. Have a great trip!
