The art of living.Galleries have opening hours, and museums also prefer to close earlier rather than later. At the Schlossberg Hotel, located at the foot of the Schlossberg in the heart of Graz’s old town, there is certainly something to see around the clock. Helmut A. Gansterer put it this way: “This hotel gives breadth to the soul. It is the finest art hotel in Europe. There is no other with such a concentration of contemporary originals in perfectly restored architecture and furnishings.” Business hours of reception: Every day: from 00:00 to 00:00 .
