The host advertised air conditioning. Air conditioning was twice listed in the ad. Air conditioning was essential for us because we were visiting Positano in August, a very hot part of the world during a time when there was a heat wave. If there was no air conditioning, there's no way we would have stayed at the location.
When we arrived, there was no air conditioning, only a small fan. The host told us we could go elsewhere if we wanted, but it was peak tourist season in Positano, and finding somewhere else would have been virtually impossible. As we expected, our stay was incredibly uncomfortable because of the extreme heat. Sleep was often quite difficult, even unbearable, because it was so hot.
We're glad to see that the host has removed references to air conditioning on her ad. Hopefully, future guests have a better experience as a result.
