Excellent choice for a DC visit
Last year when we visited DC we stayed at a much more expensive hotel in Alexandria. This year we decided to cut down our metro travels and stay closer. The Hilton Garden Inn is literally right across the street from the McPerson Square Metro station (and a Five Guys Burgers). Our two bed room cost just over $200/night including taxes which I thought was very reasonable for the location. I would have preferred queen size beds, but all they offered were doubles. Staff was very accomodating when we asked to be moved to a quieter side of the hotel after the first night. The road noise is loud so if that is an issue for you make sure to ask for a quieter room.
