TL;DR VERSION:
Great value; as described; thin walls.
LONG VERSION:
The place was as described. We knew what we were getting into by paying $100 or less a night—we figured we just needed somewhere to sleep at night.
The host was responsive when we were having issues with the heater; we were able to quickly get it back up and running with his instructions.
It's a great value if you're looking for somewhere within walking distance of the French Quarter. It's also right across the street from a nice little coffee shop.
Please know: it really is VERY small, and if you have back problems, the bed is certainly not the most comfortable. Felt almost like a foldout couch without the couch.
I also highly recommend earplugs—the walls are very thin, and because there are 3 units right next to each other with (locked) connecting doors, we could hear EVERYTHING from our neighbors through the thin walls and beneath the doors, early morning to late night. One of them started singing at 7:30 am!
