You may grumble over the unusually high cleaning fee (we were staying only 2 nights before attending a funeral in Arlington National Cemetary) or the free alarm clock in form of the trains starting around 6:20 am, otherwise it is really difficult to find anything negative to say. The location is great (we did not use the thoughtfully provided metro cards as the place is just a short walk to the Mall and museums), the place was spacious for 4 adults and 2 children, well equipped and the communication was easy. The parking permits saved a lot of hassle, a Whole Foods grocery is conveniently just a 10 min walk aways. Overall a great stay and we collected some wonderful memories.
