Francesco & Liliana's place was great! I stayed there with one friend, but it could easily have housed several more people. Francesco was good about communicating before the trip and helping answer questions about the logistics of travel from Catania. The apartment was nice and clean, the availability of a washing machine was a nice touch which allowed us to pack more lightly. Francesco was out of town when I arrived, so he arranged to have his brother Giovanni pick me up from the train station. Most of all, the porch was amazing, and watching the sunrise every morning or sitting out there with a glass of wine and an expansive view of the Mediterranean was perfect.
Be advised, the walk up to the apartment from town really is steep, although not too long. We were relatively young men in good shape, and we arrived home sweaty most days even in the cool evenings of late March. I enjoyed the hike, and it helped to work off all of the cannolis, gelato, and pasta I was eating, but if you aren't interested in some mildly strenuous walking just to get home, you might want to consider other transportation when you are there (there is a public bus which can take you most of the way home from the center of town).
