We stayed there over the summer as we had tickets to a golf tournament nearby. The hotel was very nice and modern. Better than we expected although the overall neighborhood was not as nice. It wasn't dangerous or anything. Mostly strip malls and the like as opposed to a business district or suburban feel.
The hotel was very modern looking. There is a very good restaurant in the hotel were we had a surprisingly nice dinner with wine. Otherwise, a comfortable night's stay and what you can expect from a Marriott. The beds were a little soft for my taste but not uncomfortable and the prices are very reasonable. They were less expensive than other Marriott's the area but feel just as nice.
They are doing a lot of road construction right around that area so my 2011 navigation system got a little lost. Sadly, no free wi-fi, at least on weekdays.
I've read about some bedbug issues in some hotels around the DC area but our room was clean.
