Marriott Marquis Washington, DC

Boasting more than 100,000 square feet of event space and direct access to the Walter E. Washington Convention Center via an underground concourse, the Marriott Marquis is well-suited for business travelers. But that doesn't mean you won't find leisure travelers here, too. After all, the hotel's location near Penn Quarter and the Verizon Center offers a convenient perch for sightseers. Aside from the hotel's address, recent guests also praised the accommodations, not only for their amenities, but also for their cleanliness. Rooms are outfitted with minifridges, flat-screen TVs and, in select accommodations, floor-to-ceiling windows. For more impressive views, lodgers suggest booking a room on the upper floors of the hotel. This Marriott outpost also offers three on-site restaurants and a lobby bar, but most visitors suggest dining at one of the stellar neighborhood eateries instead. When you're not working up a sweat walking around the city, get your fill of exercise at the 8,000-square-foot, bi-level fitness center. And if you're a Marriott Bonvoy member, consider upgrading to the M Club lounge, which sits on the 12th floor and provides complimentary breakfast, hors d'oeuvres during the week and 24-hour access to snacks.
