We stayed 4 nights. The staff were friendly and helpfully, although we had a seamless stay so no issues arose. Our room was mostly clean except some pieces of Oreos around a nightstand. The bed was comfortable, I like foam pillows not down or synthetic fiber so I didn't like the pillows but most people would. The halls and elevators were clean and quick. The pool was cleaned and staffed with a lifeguard, it wasn't warm enough for me but it was comfortable and the kids didn't notice. The hotel itself was quiet, you could hear the airplanes in the morning but Rossyln is in the flight path of DCA so considering that it really wasn't bad and certainly not disturbing. Wireless worked well but you had to sign in every day. The one down side was the thermostat is a "dummy", you can't adjust the temp of the room and we were kinda cold the first couple nights. It is about 3 blocks from the metro (on direct line to smithsonian and DCA) and 2 blocks from a bus to Dulles. We didn't eat at the restaurant and we were especially disappointed it wasn't open for breakfast on the weekends (you can get room service but we were minimizing the idea for the kids to be able to eat in a bedroom). Luckily Panera and MCDonald and Starbucks are open weekends and next to the metro. Overall I would return as it was convenient, comfortable, and clean.
Took a few calls to request extra blanket. first call, they said no more blanket. How can that be for a hotel like this. Second call, they said they will bring it up. But hear nothing after few hours. Third call, they finally brought up the blanket. No sure if because we are Asia!!!!!!
