Our stay was unfortunately cut short due to the unbearable heat and lack of air-conditioning + air circulation in the apartment. We checked out after an intolerably hot sweaty afternoon and sleepless night when we were being baked alive. We couldn't open windows either due to little bugs. Imagine Florence in the summer (July) when it's 38 deg.
It is misleading for the listing to say 'Air-conditioning' when there is only 1 in the living room. It did not work. No A/C in the 2 bedrooms. The fan did not help. I would urge all travellers going to Europe to ask their hosts whether the A/Cs are actually in the bedrooms and/or if they work. Our host was very polite and tried to accommodate by saying he would look into the problem - he knew the one single A/C was not working. However, it would not helped as there is no A/C in the bedrooms.
Please read James's and Eddy's reviews below - they sum up my thoughts. They visited in May and were already complaining about the lack of A/C & air circulation.
Other that that, the apartment is actually lovely, modern, and spacious. Fluffy towels and comfy beds were nice! I suggested our host put in tissue boxes and a little more cleaning.
