I had a brief overnight stay here in August. At first, a suite was not forthcoming. After a bit of cajoling, I managed to secure an upgrade to a suite. It appeared more like a Junior Suite, as it was essentially a bedroom with a large, adjacent space containing couches and chairs. The hotel itself is nicely furnished in the new, contemporary Westin style.
Breakfast in the lounge was as
treznor described it - juices, some cereals, yoghurt, and pastries/bread/bagels. The lounge itself is not especially large, but it was open on the weekend (^).
In all, it was a fairly pleasant stay. If I find myself overnighting by DCA in the future, I would not hesitate to stay here again.
Below are some photos of the suite I was given:
