Never met Mario. Apt. is in a fabulous location in a great town. Woman who met us was great.
We had two problems. First, Mario had let the gas tank for cooking go empty so we were unable to use the kitchen as expected. Second, there is a lengthy legalistic document framed on the wall as you enter the door. It sets a bad tone. It was only from this (and not in advance) that we learned that there is an extra daily charge for air conditioning (and the heat also comes from the air conditioning). The apt. was quite cold. (No other AirBNB in Sicily has had a surcharge for heat this March.)
The legalistic document also had the wrong WiFi password, which was inconvenient.
This apartment has the potential to be a great place, but our experience of poor management was unpleasant.
Mario never offered to compensate us for the non-functioning kitchen.
