The upstairs bedroom is hot and not able to make use of the aircon. The fan they have just blows the hot air around, so pretty pointless. It was so hot up there my daughter had to sleep downstairs with me, luckily it was just me and her on a trip to Rome, but if the double is full then this would create a problem. The host needs to either find a solution or ensure that the person sleeping upstairs in the tiny bedroom is ok with being very warm at night if staying in the summer months.
