We had a great time in Sicily and the villa we rented was excellent. It is a modern villa with 3 bedrooms, 3 bathrooms and plenty of space. We rented the entire place for a group of 4 but you may easily fit 3 families with kids. For us it was a good value, we even splurged on the Jacuzzi which is great, however before you get it make sure you will spend more time using it. It is a bit expensive to just have one dip.
If you rent here also make sure you rent a vehicle, this is almost mandatory for anyone looking to visit Sicily but even more important here as it is not in reach of any public transport (unless you take a taxi or like to walk for 1h)
The location is fantastic if you love a morning and evening view, well worth the isolation. Also the towns nearby have excellent food, the only downside is that it is not exactly a tourist location, while this means excellent service at normal prices it also means that most restaurants close rather early. I recommend eating at least once in the town nearby, you will get excellent and authentic food, much better than in the tourist locations.
If you wish to spend every day at the beach be ready to drive. The nearby beaches are not great, medium at best, even Mondello in Palermo is not very good and it is also crowded. To get to a pristine sandy beach or azure waters you need to drive at least 1h and 30min up towards San Vito lo Capo.
However, if you wish to travel all around Sicily it is the perfect location as you are 5 min from the speedway and once you get on it you can go as far as Syracuse or Catania.
