I stayed here for 2 weeks back in December 2010 while waiting for a new place I was moving into to finish renovations. You can't beat the value you get at this place. For $350/week you get a nice clean room and bathroom, free wifi & cable, continental breakfast (more about that later), and your room cleaned 2 times a week. It'd also aplus that you're walking distance from the VRE station that will take you into Washington. D.C. The thing you have to keep in mind with this place that I think the other poster's have missed is that this is a motel, so yeah it's a bit run down and has probably seen better days - but you're paying for a nice place to lay your head down at night, not a resort. For the posters looking for a deal, you should call the hotel directly and not use Expedia or any of the other websites. They actually make their money by marking up cheap hotels which this is definitely that. And YES the Water's Edge is awesome. I actually discovered this place while at the hotel and still hang out there today.
Some of the drawbacks though, there seems to be a community of people living here long term that the management should probably address. They tend to congregate outside, and give an overall shady vibe to the establishment. And the continental breakfast, what a joke! Don't offer the breakfast if you're not going to put any quality food out.
My advice: if you need a cheap place to stay for a week, this is definitely the place to stay. If you're traveling from miles away with your family to visit Washington, DC you may want to consider other places if your budget can afford it. If not, take it for what it is - a motel.
