A theatrical fantasy, this room owes its dramatic effects to famed stage designer and bon vivant Oliver Messel, who decorated it with a rococo flair on an unlimited budget in 1953. Highlights such as a private terrace overlooking Mayfair; hand-painted, silk-lined walls; gilded moldings; and a bed festooned with breathtaking swags and golden acorn finials continue to attract a regal clientele. $5,120 per night. 011-44-20-7629-8888, www.thedorchester.com

The Bottega Veneta Suite
The St. Regis Hotel, New York City
With windows that overlook Fifth Avenue, this beaux arts hotel is just the place we’d expect to find an ultraluxurious suite designed by Bottega Veneta. In quintessential earth tones and soft leathers, and utilizing clean lines and natural elements (limestone floors and New Zealand wool carpets), this two-bedroom getaway dazzles with a sophisticated tranquility. While its furnishings include exclusive Bottega Veneta (such as a leather-sheathed dining-room table), much of the hotel’s existing furnishings were used after being reupholstered in mohair velvet and Ultrasuede. $5,500 to $6,500 per night.
