Looks like 2405 Conoy Street is available via Keller Williams:
2,382 sq ft
$344 per sq ft.
Zillow also has it up here.
Sq footage seems a little low for a three story unit, but that's what comes up on the Alexandria Real Estate page.
I wonder why this one hasn't sold. The photos look nice, and it has a nice back deck. Kitchen looks really nice.
