I was in town for a conference being held at the Westin. It was really convenient to be able to stay right on site. I arrived a day early to do a little sightseeing. The 10-min walk to the Metro station wasn't too bad but the 40-min ride into DC itself would've been a bit much if I'd only been in town as a tourist. The staff were incredibly helpful and very friendly throughout my stay and I thought their reward system for refusing housekeeping was innovative ($5 voucher for their food/drink establishments for every day you don't need housekeeping). The only thing that would've made it that much better would've been free wifi in the rooms.
