The Americana Hotel -- Best Bargain Hotel in DC area. Located in Crystal City, Arlington County, VA. Near the Pentagon and Arlington Cemetery, just across the Potomac River from Georgetown and downtown Washington DC. 5 minutes walk to the Crystal City Metro station. Free parking, free airport shuttle for Reagan National (DCA), free wifi, free minimalist breakfast. (My personal pick whenever I visit Washington DC on my own dime.) Sputnik-era exterior, but updated rooms with great bedding.
