This villa is small but extremely well organised so it actually absolutely ok for a family of 4. It enjoys a large terrace with a fantastic view on the sea, it is fully equipped including dishwasher washing machine and air conditioned. It has free wifi and a fixed phone, while GSM signal is weak.
The magic of this location is that you have 3 wonderful beaches at 5 minutes drive. And with 30 min you can go to probably the best beach of this area at Torre Salsa. What you may miss is a nice town or village close by to go out in the evening. In this case the best option is Sciacca at 45' drive (worth a trip).
Tommaso and Sarah will make you feel at home, and take care of everything you need for you (like doing the shopping so you arrive and have some food at home) or the accommodation (like kid's bed or extra chairs etc.).
The other advantage is that in the same area they rent 5 villas so you can go here with friends or extended...
