The Jefferson, Washington, DC is a boutique hotel located at 1200 16th Street NW in Washington, D.C., in the United States. It has also been known as The Jefferson Hotel. 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. It became better known after a 1980 renovation, and became a Washington landmark. It was sold in 1989, 2000, and 2005, and underwent a two-year, multimillion-dollar renovation that revealed the building's original atrium skylight. It reopened in 2009.
