Jay's place is pretty much like a small youth hostel in one of the more quite neighborhoods of NOLA. He wasn't there when we arrived, but we met a few hours later. He did however text us instructions on how to enter the house and such, so that was not a problem. Jay was very friendly and easy going, and he gave us a lot of great recommendations about the city.
It's a bit too far to walk downtown (to the quarters), but it was a 10-15 min walk to catch bus 16 which takes you there directly. Lyft also worked well and was about $10.
The house itself is a bit ragged and crooked, and almost all floors are carpeted. That in combination with the humidity can give the impression that it's not very clean, when I actually think it is. The humidity isn't really something one can avoid while in NOLA.
We parked our car in the street and felt safe doing so. There is a driveway where you can park, but it's cracked and as our car is very low we didn't want to risk scratching it.
With these things in mind the listing is pretty accurate, and we had a good stay!
