Frommer's "The hotel is primely located on Pennsylvania Avenue near theaters, the White House, the National Mall, and restaurants"
Zagat ""Popular for conventions" but also "comfortable for families", this "wonderful", "well-organized" chain link hits the mark "both for business and pleasure" with a "fantastic" location a few blocks from the Mall ("close to everything") as well as "comfortable", "well-appointed" rooms -- some offering views of the Washington Monument and balconies; service nets mixed reviews (from "highly attentive" to "curt"), but perks like an indoor pool, two on-site restaurants and "lots of dining options" nearby lure loyalists to keep "coming back"
Star Service "The all-purpose restaurant has a familiar menu of fish-and-chips, Marriott burgers, New York strip steak and breakfast buffets"
Oyster "Dining options feature a full-service restaurant, evening cocktail lounge, and 24-hour room service, though there's no on-site fine dining"
