Good hotel. Rooms are clean and well appointed. Hotel staff were friendly. I was here during a large conference, but the hotel seemed to manage things very well.
The hotel is next to the White Flint Metro stop, so you can get here by train from National airport. It takes about 50 minutes. If you come into Dulles airport driving is the only option. A cab is about $60.
There a large number of restaurants a short drive away. If you don't have a car your choices are limited to the hotel and some nearby fast food.
I would definitely stay here again.
