Room ok, everything else mediocre
Stayed here two weeks ago. Upon check-in I was told that internet service was down in the room and only available at the bar. I then asked to be moved to a room that had internet service and was told it was down in every room. For a business traveler not having internet service isn't the best.
Made it up to my room, really small, although clean.
Went down to the bar to eat dinner, ordered a chicken sandwich and local beer. Food was horrible, not even edible, beer was good. I would suggest finding a local restaurant to dine at.
All of my other stays in DC have been at the Capital Hilton which is MUCH better then the DoubleTree on Rhode Island Ave. If you have the choice, opt for the Capital Hilton.
