I gave mixed reviews here for the following reasons:
1) I'll give the owner the benefit of the doubt and assume it was as great as it looks in the pictures. I give it high stars for that.
2) I never reached the place. It was hard to find up on the side of the mountain. And the last 100 meters of the one-way road leading up to it was very steep, curvy, and without safety railings. My car stalled on the way up and was having trouble making the turns. I felt in danger of my life and was too afraid to continue. So I reversed all the way back down. I was truly afraid to go all the way up - and this is the first time I've ever canceled an Airbnb out of fear.
Maybe local Sicilians are used to roads like this, but I am definitely not. If you aren't used to them, or are afraid of heights, you might not feel comfortable trying to drive to the location.
