One of the worst check-out experiences I have had in a month of travelling around Europe. The host didn't mention anything about the air conditioning, but when we checked out he said he would call the police and make us pay a fine. It was funny that the host used English when threatening and taunting us, but refused to use serious English when communicating and explaining. If it is only a Milan rule, please advise in detail upon arrival. Please also advise if the air conditioning is just for decoration. Btw, the moka pot was not cleaned and already stank so we did not use it.
