Caterina's place is beautiful. It has almost everything you could need and the location is great for beaches, tourists sights and to witness sicilian life. Caterina was prompt with her responses to our questions and very kindly organised the substitution of our mattress after the first night - we found it to be very springy and it was uncomfortable to sleep on.
Caterina left a book of information for us as she wasn't there to greet us and her father speaks no English. This was basic but fine. Personally the benefits of airbnb for me is the contact; the little bits of information you get from the local host, so I would have preferred to have been able to have some conversation with the host in person.
We did have some difficulty find out certain bits of information - what beach to go to on windy days - it can be very windy and the beaches become impossible in strong wind - there is however lots of little coves to explore, we found a place locals go to but it took a few hours of searching.
Overall this was a nice stay in a good location. Caterina's place is beautiful decorated, the shower is good, the bed (once the mattress was changed) was very comfortable and the surrounding countryside made a stunning backdrop. I would recommend.
