Jay's place on Church St NW was terrific. We stayed for just over a week for a mix of personal and work.
The condo is bright, modern, and clean. (I like airbnb's like this one that seem designed as rental properties so you don't feel like you are living among someone's personal stuff) We got good use out of the sun-soaked deck with two chairs and table (and there is the second, smaller deck, too). We used the dining table to set up two workstations since we were doing a mix of personal and work.
The location is incredible (and I say this as someone who lived in D.C. for 10 years): easy access to Dupont Circle, 18th St NW, 14th St NW, White House, etc. In terms of parking, Jay offered to facilitate a paid spot (which we might use next time), but we got by with street parking: most streets in the area offer two-hour parking from morning to evening and unlimited overnight parking, so if you use/move the car a few times midday, it works, and we never had to circle more than max 10' (usually much less) to find a spot.
As a host, Jay was very responsive and communicative.
We'd stay here again without a doubt.
