This is the Seven Corners area, and it looks like your townhouses are just inside Fairfax County on the Arlington County border. Not sure whether crime is a big issue, but the area is home to one of the larger concentrations of low-income immigrants (mostly Hispanic), and the schools will naturally reflect those demographics in their test scores. I can't tell which is the neighborhood school, but Bailey ES is nearby, which offers a magnet program for arts and sciences and a Spanish immersion/ESOL program.

Willston shopping center is a fairly drab place, with a large Safeway but not much else of interest, except for the Target store around the corner that packs them in. There is a very busy Home Depot right across Route 50, along with the best dim sum restaurant in the area (Fortune).
Since you live nearby, you should definitely check the area out in person.
