Corinthia Hotel, London: Royal Penthouse Suite

The largest two-bedroom hotel residence in London, the Royal Penthouse at the Corinthia radiates an understated refinement from within its 5,000 square feet. Overlooking the Thames with 180-degree views of the city—making excellent use of its tucked-in locale on Whitehall Place—the suite has a private kitchen and wine cellar, as well as a terrace with a fire pit. A spiral staircase leads to the bedrooms with their king-sized beds, and the bathrooms sport honey-hued onyx and marble. (Thanks to an in-room spa-treatment pod, there is no need to go far if an appointment with the ESPA Life spa is in order.) The furnishings are (fittingly) bespoke, like the Makassar ebony dining table and walnut bed frames with leather detailing. From $28,479; Whitehall Pl.; 44-20/7930-8181; corinthia.com.
