Clean hotel with a ton of activity. Cutting edge minimalist design, but clean large room with giant individual bunk spaces for our college-age kiddos. Fun decor in the lobby with record players, old TV's, and artifacts. Right next to amusement park and convention center. Nearby restaurants and bars. A little bit of a hike to public transportation and Vienna art, shopping, and opera, but Uber quick to respond with a 15 Euro ride to center of city.
