A grande dame hotel that's hosted presidents and diplomats for over a century, the 332-room Willard is a D.C. icon dripping with history just two blocks from the White House. The exceptional staff and opulent lobby are highlights, as is the popular Round Robin Bar. Business Perks: The Willard is best known for its history -- a hotel has occupied the plot of land since 1816 -- but it's also a solid business pick, especially for those with liberal expense accounts. It's located in the heart of "old downtown," just blocks from the White House, the Mall, and two Metro stations. And as you'd expect from a hotel owned by InterContinental, the hotel caters largely to business travelers, with amenities like property-wide Wi-Fi, 20,000 feet of meeting space, and a business center with audiovisual equipment available for rent.
