Just spent the night at Dulles. I couldn't hear the airport but guests in the hallway sounded like they were in my room with me.
Had trouble with the wireless internet in the room. Three calls and a visit to the front desk and then an "engineer" in my room couldn't solve the problem. Had to call the provider for a work around. The front desk staff did "comp" me for the internet after that. Otherwise the internet is $12 per day.
Restaurant was small. Breakfast buffet had runny scrambled eggs for $17.
Other than that, the room was nice and the staff tried to be helpful.
