My middle school band group spent a few nights here while in Washington. This place was decent, and was about 30 minutes from the city. I would recommend staying here if you don't want to stay in downtown. The location is great because you can come from 495 to here without going through a traffic light. HOWEVER, the downside was that the hotel wifi is $12.95, which is quite expensive. Overall fantastic in terms of location.
The rooms are not very large, just to let you know.
