We decided to go to DC spur of the moment and instant-booked Dennis' place because of proximity to Yards Park (Bluejacket brewpub and other things). It is a tiny hike to the metro, but if you know the area it's a great value for a place so close to everything (and there is a bus around the corner that goes right to the National Mall).

He was A+ incredibly responsive and got us in and with a parking pass in literally minutes after we booked. The place looked even better than it did in the pictures, and the bathroom (while pretty hot because of the skylight) has a skylight. In the shower. And the shower is one of the ones with sideways jets. It was amazing on a +90 degree day. We didn't meet Dennis but we met his very friendly wife and extended family when they came by to watch soccer (we turned in early, worn out by the heat).

Only reservations: 1) the heat. The room was hot when we arrived, then nice and cool when we came back in the evening, but became rather hot in the middle of the night. Perhaps a floor fan would help with this and white noise when there are guests. 2) the deposit. I know this is an insta-book so there is less vetting, but a $200 deposit seems a bit much for a pretty standard space...I only have a $200 deposit on my own apartment.
