We checked in at early of July, when the average temperature in Florence was 39 degrees. We according to the Host request turn on the air conditioner all day and set to 18 degrees, but the air conditioner was not cool enought. The room temperature was estimated to be about 27 degrees. We requested a fan but the Host said that there is not fan. Since the airbnb is on the main street, it is very noisy after opening the window. Although he also sent a mechanic to check it, it still didn't help. The Host also suggested that we find another hotel/airbnb, but since it was the peak season and we booked the train left at 8:00 in the norning, so we couldn't find a suitable hotel/airbnb at all. Because the bed was in the loft, the temperature was higher and we couldn't sleep well at all. The Host finally said that the very hot outdoor temperature affeced it in the midsummer, the indoor temperature is never cold. But we had also travelled to Roma & Milan at the same trip, there's temperature is not lower than Florence, there's airbnb doesn't have to be open all day, and the air conditioner is very COOL. We are very disappointed with the host response.
