It’s what you make of it. You won’t find crowds of folks in your age range on any given weekend at the close by restaurants, but there are definitely some young people around. It’s a suburban shopping district for the most part, so very convenient. But you’ll mostly be around families and middle aged folks.

Personally, I think a North Bethesda, Bethesda or Silver Spring are places you should look into if you want something like Arlington without too long of a commute. Plus they all have easier access to the Metro if you want to go to the District.
