Stayed at Residence Inn National Harbor during a convention. Convention was at the Gaylord which is directly across the street. Residence Inn was much less expensive. Don't really need a car, unless you want one. The National Harbor area has several restaurants, a CVS grocery and you can take the water taxi to Alexandria to catch the Metro or go to Mount Vernon or Georgetown. Residence Inn suite was clean, had kitchen with full size refrigerator, dishwasher, microwave and two burner cooktop. Includes dishes, flatware, pans, etc. Housekeeping is available daily, if you want it. Would definitely stay there again! Note......the frozen French bread pizza needs to be cooked in a toaster/conventional oven which is NOT available here!
