Our family spent two weeks at Villa Leone in December 2014. There were 9 of us in total (6 adults and 3 children), and we truly had an amazing family vacation.
The Villa itself was clean, spacious and comfortable. The 'backyard' had a private pool, hot tub and direct access to the beach. It was beautiful with plenty of space for eating, swimming and relaxing. The Villa and grounds were extremely well equipped and maintained and the incredible staff took care of our every need without delay. It was like staying at a private resort.
Mr. Leone's recommendations with regards to travel arrangements, restaurants, attractions and options (i.e. private chef, etc.) were also extremely helpful and appreciated.
Overall, if you are looking for a vacation that has everything but crowds, I would highly recommend Villa Leone.
