The Grand Hyatt Washington is a hotel in Washington, D.C., in the United States. The 897-room hotel, located at 1000 H Street NW, serves both tourist and business travel. From the time the hotel opened until 2003, it was directly across from the Washington Convention Center and served as a "convention headquarters" hotel for many conventions. The convention center closed and was demolished in 2004. CityCenterDC, a major office, residential, and retail complex, now occupies the site.
