We had a great stay. The place was clean, quiet, comfortable, and well maintained. It was small for us and our four teen/young adult sons. Fortunately, we had only a carry one each plus one other suitcase, so did manage to find places for all of our stuff. And, there was extra sheets and one extra comforter so one of them slept on the couch.
We do wish we'd been a bit closer to the National Mall since that's where we spent a lot of our time. We didn't have a car so were relying on public transportation, which took about 30 minutes that included 5 to 15 minutes of walking on either end. So not too bad, but it added up. And, while we felt very safe at the apartment and in that neighborhood, there were short stretches on the way to Bening St for the bus & H St trolley/street car or the Stadium-Amory metro station that we didn't want to linger in. ( Online map directions always sent us to the Stadium-Amory metro station; never NoMa-Gallaudet.) The best experience was taking the D6 bus to go to the US Capitol...it wasn't crowded even at 8:30am.
