Overpriced and needs renovating!!
I was in D.C. for a week over the 4th of July for a convention. The hotel was chosen for our delegation. This was such a disappointing stay. The hotel is completely outdated. ( We had heard that renovations had been promised) The room was dingy and humid. The bathroom floors were grimy and the bed linens were torn. The room also had a very musty smell to it. While there was a fitness center there, only 1 of the three treadmills there worked correctly. (One did not work and the other was not level) 
There was a small "To Go" station in the lobby, however it was only open until 2:00. The pub food was ok, however the breakfast service on for Sunday morning Brunch was so poor. Apparently the table we were seated at did not have wait staff and no other server would help us because it was not their station.
The Hotel is does have a metro stop and is a five minute walk to the Smithsonian Mall. Other than that, there is not a lot around this hotel. If you do need to stay hear, make sure you get a room that does not face the train tracks. Otherwise you will hear the train whistles in the middle of the night.
Overall, I would not stay here again.
