Diplomats and heads of state bed down surrounded by antiques, jewel-toned silk walls, crystal chandeliers and marble bathrooms at the 138-room Hotel Imperial Vienna, which was built as the residence of the Prince of Wurttemberg, a European aristocrat, in 1863.
Rooms feature marble bathrooms, heated floors, rainfall showers, silk-threaded wallpaper, and gorgeous oversized windows (all the better to savor those views).
