We have stayed here many times and while the location is truly great for touring Washington and very close to the subway, the property is really starting to look tired and worn. Fortunately, it appears that Marriott has designated the hotel for updating and they are about to embark on a property wide remodeling effort in the fall.
The service and staff are always top shelf at this hotel and no matter where you are going, you will find yourself centrally located. We were visiting our son in Arlington, went to the National Zoo, a Nationals ball game, visited the Newseum, ate several fine meals out and were able to drive or utilize the subway without a problem. Subway entrance is only a couple of short blocks away.
The breakfast is pretty standard but always a nice option to be able to eat in. There is no pool, either indoor or out but there is a farily adequate fitness center. Additional $14 per day charge for parking. There are laundry facilities on three separate floors.
Even in its current state, this is still good value for the money given the property location. The nightly cookies they put out is a nice touch.
