We are staying in Sicily for the 4th time with kids. Every time we have rented a new house - also this year so we can compare.
The house is located 5-7 minutes walk from the great sand beach in Fontane Bianche ( Lido Fontane Bianche ) where you can get everything you need. Water is very clean and the depth of the sea increases very slow what is very comfortable when you stay with kids.
Rooms in the house are very big and have all you need. 2 showers in the house and 1 outside. Great coffe machine. BBQ. Very nice terrace on the 2nd floor where you can rest in the end of the day.
We didn't have many questions as we were staying there for the 4th year but if we did we got very fast answers or assistance if it were needed.
20 minutes from the house there is a Golf Club ( I Monasteri ).
20 minutes from the house there is a AquaPark.
In the evening we usually went to Sicarusa for dinner ( 20 minutes by car) - the city is very very beautiful with many restaurants.
We also made some longer trips to Taormina, Etna, ect so we totally didn't have questions where to go if we wanted to.
