We've spent 4 days at the farm as a family of 4 (parents + 11 and 4 year old boys) and we simply loved it. The apartment was clean and had everything we needed. The pool is shared with other people staying on the farm (I think there are 4 apartments there), but there was enough space for everyone.
As a bonus you get a breakfast each day which is not common on Airbnb.
The location of the farm is quite rural and you need a car to get there. It's a good base to visit Siracusa, Etna and Catania.
