Disclaimer - we were in NOLA when it was the coldest you'd ever expect it to be (30s-40s).
Unfortunately the heat wasn't working when we stayed at this airbnb. The owners tried to make it up by giving us a free night and offering to give us a refund if we found other accommodations, but being a short 3 night stay, we decided against the hassle of rearranging taxis and moving our stuff around. That said, it was cold. The owners had a space heater but it required propane that wasn't provided, so we spent 90% of the time under the covers.
Pros: This place has an INCREDIBLE Location!!!! This place is spacious (way more spacious than a hotel room) and has a washer and dryer. The owners of this airbnb were fairly responsive and seemed to genuinely care about our experience.
Overall, I would book this unit again if it were warm outside. if we come back in the winter, you'll find me in a hotel.
