We loved staying at Thomas's AirBnB. It was very clean and roomy, and the bed was SO comfortable! He was very personable and gave us some good info, as well. The streetcar dropoff was just a couple of blocks away (pickup in other direction a couple more), and there was also a Waffle House just a few blocks away. The JET bus dropoff was about 4 blocks away, and WAY cheaper ($2) than Uber or Lyft. We took it there and back with no problem. Really no need to rent a car, between the CTA Jazzy pass ($3/day) which covers streetcars, buses (but not the JET bus, which is a separate system) and ferries.
Highly recommend this location! Price was reasonable too, even though the Mardi Gras season had already started.
