We stayed at Franceso's place for only one night but it seems like an ideal location to explore the south of Sicily. The village is very nice and quiet, the parking is provided and it is very easy to get to Agrigento, Valley of Temples or the beaches.
The place itself is truly special since it is decorated in unique style full of Game of Thrones, Lord of the Rings, Star Wars and every other fantasy story ever memorabilia.
The only potential issue for people staying longer could be the infrastructure - for example, the toilet cannot be used for disposing paper so the bin next to it should be used. Also, water pressure in the shower is very low.
Small tip: If you are looking for local food, Centesimo is not a good choice. Francesco recommended it to us as we were looking to buy local pistacchi but we ended up coming home with pistacchi from Iran (which is a REAL pitty if you are in Sicily) - we didn't additionaly check the food origin on the spot so this has been a bummer.
