As other reviewers have said, Claudia's place is even more beautiful than the pictures - the pool is shared but there is plenty of space with lots of seating (and there were only a few people there to share with a couple of days, so no problem) There are two supermarkets nearby - the Simply one is a lot nicer quality food than the discount one. The Canadian bar does great coffee and pastries across the road, while the Miseria e Nobilita does the best pizza we've ever eaten, it was delicious, about a 10 minute walk from the house. Everywhere we ate was lovely though, and perfectly located for Etna tours. The pool is fantastic, and everything is clean. Don't forget mosquito spray (there are guards on the windows and Claudia left us a mosquito coil to burn, but we did get bitten a bit).
Muhamed the housekeeper is a pleasure - he kept out of the way and gives you space, but is also very friendly and says hello. the parking is as others have said fantastic too - definitely get a smaller sized car if you aren't comfortable driving (in sicily in general) as there are some narrow streets! I would recommend staying here definitely as it is beautiful and relaxing, very comfortable.
