This is my husband's and my go-to hotel during our many trips to DC. It's 2 stops on the Metro from Reagan (and spitting distance from the Metro entrance), and a 5-10 min cab (or Metro) ride gets you into the heart of the city. It's also a huge bang for your buck - the rates for the Washington DC and Georgetown locations are at least twice as high.
This particular hotel is a little more nondescript than other locations we've visited, but the service is consistent with what you will find across the Ritz family of properties. The property is clean, but tired. The carpets could use replacing (they are ragged), walls could use some touching-up, and the furniture finishings are also a little worn. There is no spa here, unlike many locations, which for some, could be a downer. They have finally gone from the Ritz-branded toiletries to what you see in some of the higher tiered-properties and offer Illy coffee in the rooms. The club lounge offers food in some sense from 6am-10pm, and the hostess, Sonia, is very good with accommodating special requests/dietary needs while you are up there. On our most recent trip, we needed a late check-out -- the staff gave us until 4pm and let us stay in the club lounge until we were to leave for the airport. Like I said, great service.
