Many of the iconic features of the historic Old Post Office building were preserved during its transformation into a luxury hotel, which features 263 guestrooms and suites averaging more than 600 square feet, making them the largest in Washington D.C., with lofty 16-foot ceilings, soaring windows, beautifully restored historic millwork, and glittering crystal sconces and chandeliers. In addition, two extraordinary Presidential Suites are located in the historic former offices of the Postmaster General. At 3,500 and 5,000 square feet, the three-bedroom suites are among the largest in the country.
