We made a reservation in the winter, and had *zero* heating. We tried to operate the central heating but it did not work/respond. Host was totally unresponsive. Least they could have done was delivered a sufficiently large space heater. The host had many other properties on Airbnb - why not switch us to another one that had heating? Was impossible to get a hold of her.
Luckily Airbnb gave us a full refund which we commend. Good customer service from Airbnb support.
