The Pool at Hyatt Regency Washington on Capitol Hill

"The fitness center and indoor swimming pool have recently been renovated and are quite cool, but you'll be charged and extra around US$14 per day to use them"

"This large, 834-room Hyatt comes with a beautiful atrium lobby, a large, heated indoor pool, a superb fitness center with new equipment, a 24-hour FedEx office center, and a convenient location, close to the Amtrak station and the Capitol Building"

"Popular with tourists and the business class, the hotel offers an indoor heated pool and restaurant and lounge that are set within a five-story atrium, alongside its 838 well-appointed rooms"

"The 8,000-square-foot fitness center has an indoor heated lap pool"

"A heated stainless-steel pool long enough for lap swimming occupies a glassed-in conservatory, while the adjacent fitness room overlooks it"
