Before arriving I twice asked Berny if the apartment had Aircon. The first time he did not reply but the second time he confirmed that the apartment did have Aircon. When I arrived I was greeted by Erica and I asked if the apartment had Aircon and she replied "not really. It's old and doesn't work well but there is a fan." That shows that Berny clearly knew there was no functioning Aircon even though he subsequently claimed that this was a new problem. After I phoned Berny a (not very effective and extremely noisy) portable unit was brought to the apartment. I was then told that the actual Aircon unit (which is really a duel use radiator and is only in one room of the apartment) would be repaired...on the day I check out. I was in Florence during a particularly hot weekend and the stay was extremely uncomfortable. Had Berny been honest about the Aircon situation I would have booked elsewhere. I recommend that other people avoid staying here.
