The Trump Organization has been selected to convert the Old Post Office in Washington, D.C., into a 250-room luxury hotel. Earlier this week, the U.S. General Services Administration made the announcement with the hope that turning the underused federal property into a mixed-use development will help the government save money. In addition to guest rooms, the property is expected to have multiple restaurants, a spa and conference facilities. Under the terms of the National Historic Preservation Act, all of the building's historic features will be retained. Work on the property is expected to begin in 2014, with the opening set for 2016.
