I did not find the Administration serious because in June I booked, according to an offer advertised in the Giornale di Sicilia, 4 days in September for an amount of 400 for two people by paying a deposit of 150. In July I had to cancel the reservation by requesting the refund of the amount paid in advance. After several reminders and requests for replies and reimbursements, the Administration or whoever manages it for them has turned a deaf ear. I am disappointed and embittered.
