10min by shuttle from Dulles, 45min by taxi from downtown DC (85USD on avg). Internet wi-fi connection works well from ground floor, it's much slower (well, too slow) from the rooms. Rooms have everything you need and front desk staff is helpful. Breakfast is great but I would recommend to have lunch/dinner outside since the menu is limited to sandwiches and few salads. Swimming pool is really small (I wouldn't call it "swimming"...). In summary, good location for business except for the speed of the network from the room.
