I would deeply recommand a stay in Francesco and Stefania's house, for at least 2 or 3 nights! They are very kind persons and this is from far our best airbnb experience in Sicilia! The quality of the services and the breakfast they prepared us on the terrace were far beyond what we expected.
This area is quite different than what we saw in the coast and I wish I would have scheduled on our trip a few days of hiking.
The house is lost in the mountain, however we reached Cefalù in just 30 minutes!
