I've stayed here multiple times (10+) over the last 2+ years. Very good overall. Odd-numbered rooms have a nicer view (overlooking the man-made lake vs parking structure). I like the large walk-in shower, and breakfast buffet is good. Good fitness center, which I've usually had to myself. It does seem like most times I've stayed here, there have been large groups of school kids, but always well-behaved (i.e., quiet) and no issues aside from crowded elevators in the morning. My favorite local hotel is still the Hyatt Reston Town Center, but Westin is usually half the price, so it gets most of my business.
