Be advised, there is no front desk personnel and unlike other hotels in Sicily, the check-in process is not modernized (management physically must meet you at the agreed-upon arrival time). Also, you will have to find parking in the area, which can be rather difficult to find since it's a very busy area.
The issue in my case is that I arrived to the local airport at 7AM. Since we couldn't check-in at that time, we decided to rent a car and go hiking to the Etna volcano (where I had no cellphone signal). Once leaving the volcano, I advised to owner (via WhatsApp) that I would be arriving later than originally anticipated (1.5 hours later at 16:30).
Upon arriving, the owner went on a verbal tirade, speaking very quickly with an aggressive tone, for (i) arriving later than expected (she had personal obligations that had to be put on hold) and (ii) for not following her parking instructions (it was difficult for me to concentrate since she stressed me out with all her messages and consecutive phone calls).
I have never been treated this way by a hotel, apartment, etc. I believe the owner can be very nice as long as you don't change your time of arrival.
