We very much enjoyed staying in this villa. The house is spacious, certainly big enough for the four of us staying. The house is fronted by a large veranda on two levels; we enjoyed eating outside most days, including breakfast, and this was in mid-October.
It is a clean and tidy property, the only potential downside for larger groups is that there is only one bathroom.
There are nice views of Etna and out to the Med, though you do not get a full view of Etna as it is partly obscured by a lower ridge.
The road is very quite, though I agree with a previous reviewer that the entrance is quite dangerous.
We found no great problems getting to places from the Villa, Zafferana is not too far from the nearest Autostrade. Be prepared for the fact that the Autostrade is a toll road, though we never paif more than 3 Euros; most journeys we did were less than 1.
If you want to enjoy Etna, make sure you bring appropriate clothing - it was very cold at the car park, and that is nowhere near the top. Make sure you visit Etna!
I also think that a car is a must for this part of Sicily, we would have struggled without one.
