I consider that block to be Van Ness...I suppose it's just as close to the Tenleytown Metro but being situation around CT ave rather than WI means I think of it as an extension of the rest of van ness. Definitely its own thing (with lots of housing / no retail separating it from the part of van ness near the metro) but until it gets its own name, I call it van ness. Or I call it "the area by politics and prose"
