Thanks for posting your experience. I had the same listing showing up but was not sure how far on the edges of that box it would be. Reading your post, I took the leap and got the same location.
Confirmation for another 4* DC (Capital Hill - National Mall) Hyatt Regency Washington on Capital Hill for 8/1/2015 - 8/7/2015 @ $97/night. (Yea same date range really confirmed it for me).
Edit - I also made sure to use the HOTWIRE link here to make the reservation.
