We booked through Orbitz and got a cheap room rate (which I assume was because it was a weekend stay and off season for tourism). When we arrived our room was upgraded to an executive suite, which was hard to fault. The room and its factilities were great and the bed was very comfortable.
Location wise, very close to the White House and a Tube Stop.
I would also recommend the Restaurant located in the hotel entrance - the food was excellent.
