The Pool at Rosewood Washington DC

"Luring well-heeled sybarites with a long list of amenities, this luxe boutique overlooking the C&O Canal boasts airy guestrooms and suites outfitted with hardwood floors, Pratesi linens and Illy espresso machines, as well as bathrooms featuring deep soaking tubs and rainfall showers; museum-quality artwork adorns the walls, there's a rooftop bar and infinity pool offering views of Georgetown and service is bestowed courtesy of Personal Assistants on call 24/7 to attend to every whim (including arranging in-room spa treatments)"

"A rooftop lounge includes a fitness center, indoor/outdoor relaxation pool, and views of Georgetown, the Kennedy Center, a bit of the Potomac River, and the Washington Monument"

"Much of the hotel is open only to guests—the rooftop bar, pool, and boutique gym with panoramic views of the monuments, as well as the library-like Living Room, with its floor-to-ceiling onyx fireplace and art deco chairs that beg for heavy conversations, which only accentuates the feeling of a private club"

"For guests only, the rooftop bar has a petite infinity pool, a full cocktail menu and, most important, knockout views of the Potomac River, the Kennedy Center and the Washington Monument"

"The Rooftop Relaxation Pool has an adjacent lounge, and the 24-hour Fitness Center offers access to personal trainers"
