A glass-and-chrome structure in the middle of a residential neighborhood, the Augarten has more than 400 pieces of art in every room and common area from the 1960s to works of current day Austrians. The spacious guest rooms, almost all with terraces, are decorated with a cool, lean touch, yet offer the ultimate in luxury—heated wood floors, feather beds, and eye-catching, expensive fabrics. Want to go for a midnight swim in the heated indoor pool? No problem—all facilities are open 24 hours. Breakfast is especially good, with extras like candlelight and fresh-squeezed orange juice.
