The Pool at Swann House

"The backyard pool is unique for a B&B"

"In summer, cool off in the outdoor pool, private behind a trellised wall"

"Housed in a turreted mansion dating to 1883, this nonsmoking B&B features 12 individually decorated rooms and suites, all with private bathrooms (some boasting whirlpool tubs) and some with wood-burning fireplaces, four-poster beds and decks; the location is handy for shopping, dining and public transportation -- the Dupont Circle Metro stop is four blocks away -- and freebies include WiFi, a breakfast buffet with housemade pastries and granola, a swimming pool and afternoon and evening refreshments"

"The Duomo suite has a custom-made bed and spectacular bathroom complete with claw-foot tub, elegant rain shower, and whimsical mural inspired by the frescoes in Florence; the Jennifer Green Room overlooks the converted mansion's outdoor pool and deck"

"The free breakfast has delicious hot dishes, and there’s an outdoor pool in a cozy courtyard"
