If you prefer to stay in the thick of things, the 25 Hours Hotel in the artsy Museumsquartier area of Vienna is the perfect pick. The hotel was a former student dormitory, and retains a youthful and colourful vibe. The design elements are decidedly kitschy, with a circus motif prevalent throughout the hotel. The rooms are done up in bright primary colours and there are paintings of juggling clowns and circus freaks at the headboard. There’s a rooftop lounge bar, which is a swinging place on most evenings. The hotel is at a walking distance from the 2 main museums—the Museum of Fine Arts and the Museum of Natural History.
