We had a good time in DC! The appartment was a little bit tight, but very clean and everything you need was there. Our bedroom had no window, but there is a fan in the room. The neighborhood was a little bit uncomfortable at first sight and its better to get home with a taxi/uber when its dark!
Aric is really fast in answering and we were allowed to store our luggage there for some hours after check-out, so this was very nice and helpfull.
