We stayed at this hotel for two nights in March. It is near the airport, which is great if you have a flight near Dulles. However, if you're like us and are using the hotel as a base for any reason (ours was a wedding) it is not a very good choice.
The best way to the hotel (and really the only way) involves a toll road! Also, it is not really near anything due to it's proximity to the airport. It was also understandably noisy due to plane fly overs.
The rooms were nice, beds comfortable, and the staff was great. Good breakfast!
