The Jefferson is a luxury boutique hotel located at 1200 16th Street NW in Washington, D.C., in the United States. It was built from 1922 to 1923, and was initially an apartment building. After housing war workers during World War II, the structure was converted to a hotel in 1954. Although not noted for its luxury at that time, it was the favorite of theater and movie stars, musicians, and top government officials.
