Judy's is a great place to stay for touring Washington. What you see is exactly as it is. The communications was great with Judy's responses being prompt - I don't remember any question going unanswered for longer than an hour - most never that long. There is no off-street parking so finding a spot can be a hassle, maybe, 10 percent of the time, but, in general, not an issue. The locals all drive small cars so if you have a Prius or Sorento, drive that. Eighth Street is a five minute walk, offering many restaurants. Another minute and a half gets you to the Metro - quite literally, the Metro gets one to all the touristy Washington spots, circling the U.S. Capitol plus the MGM National Harbor casino and the Pentagon further out. For Mount Vernon, one needs to drive.
I felt going in that Judy's was a wise choice for us, and, after five days in D.C., I still feel that it was.
