Li's place was great for our Jazz Fest weekend. It's clean and located in a quiet neighborhood. The home is located in a quiet suburb roughly 10 minutes driving from downtown neighborhoods. I would recommend renting a car if you plan on making frequent trips downtown, as taking Lyft would cost $10-$15 each way. If going to Jazz Fest, it's possible to walk to the Fairgrounds - it took us roughly 35 minutes to walk 1.5 miles each way.
One interesting aspect is that you need to go through the garage to enter the unit. This means when you are out and about, you need to carry the garage door opener with you (though I'm sure Li would be accommodating if you forgot). Also, note that you'll need to climb a couple flights of stairs to get to the unit. Once inside, the space is quite ample for two people, and could comfortably fit a 3rd person staying in the living room (for an extra fee, check the rules).
As a host, Li and his wife were very friendly and attentive. They provided extra towels midway through our stay without our asking. The fridge was stocked with bottled water which proved handy for the warmer days. Air conditioning and wifi worked well, and unlike some other Airbnbs there were very few required chores prior to checking out.
We would definitely stay again next time we are in New Orleans!
