We had a lovely time staying in Terrasini. The pool is very big and mostly very quiet, and the nearby beaches are great. You will need to drive around a fair bit whether that's to get to the best beaches or going out for dinner, but we found we could go to most places within 30 mins. There is a supermarket very close to the villa, and the kitchen contains pretty much everything you will need to make any meals. We stayed with two young children and they had a great holiday! Do bring some shoes you can wear in the water for the stoney beaches, but if you are looking for sandy beaches then the sea at mondello is beautiful but quite busy. We liked balestrate the best though. Always aim for a lido and pay for the umbrella and seats! For Italy we found this one of the most reasonably priced areas we have visited over the years for food and drink.
