FANTASTIC location, steps from good coffee and affordable eats, and only a few blocks from the Capitol and other attractions. Very walkable, but also close to Metro. It was COLD when we were there but the apartment was extremely comfortable and there were additional space heaters to help our Florida blood. Everything you could need is provided, and the apartment is very clean and comfortable. I walked the few blocks to Trader Joe's and stocked the fridge, the kitchen is small but perfectly functional for even an extended stay.
For the busy area in which it's located, the apartment was really very quiet most of the time. My only warning is to the light sleepers - the bedroom is at the back of the apartment and the businesses start setting up early, so there's lots of activity going on in the alley starting at about 6 a.m. If you're not planning to rise early and don't sleep through noise well, this is a good thing to know in advance. (There's not much the hosts can do, certainly not their fault - and disposable earplugs are provided in the nightstand, which was a nice touch and acknowledgement of the situation - but I'd left my noise-cancelling earplugs at home and wish I'd prepared better.) The benefit in exchange, though, is the convenience of some pretty good options very nearby for all-day grab-and-go coffee, meals and treats (get a toasted marshmallow milkshake from Good Stuff! Yes, even if it's 20 degrees outside!)
