It was 40+ degrees when we visited and host asked us to turn the air conditioning and fans off when we left the house. As you know an air conditioner takes quite a while to cool a place so with the air conditioner off all day the apartment was stifling when we returned. We were traveling with our elderly parents so we had to give them the room with air conditioner so they could sleep, my husband and I were in the room without the air conditioner. Just be aware that when hosts say that there is air conditioning... it may not be in every room and they may try to restrict the use of it. Also if you like to have a blanket on your bed you're out of luck because the bedding consisted of a sheet... thank goodness it was very hot and we didn't need one! The place however is huge and close to all in Marsaxlokk. No issues in communication with host.
