We had a wonderful time in Massimos apartment, and I would highly recommend it for everyone! Everything in it (air condition, shower etc) worked and was clean. The view was beautiful - you can see mount Etna, and the apartment looked just as on the pictures. Massimo was very friendly and easy to keep contact with during our time there. There was a store just next door and the Buda bus that took you to Naxos and Taormina stopped just outside the flat.
A good thing to know is that it might be good to have a car. We manage without though, and after finding out how the busses worked it was all fine! Calatabiano is not touristic at all. It's small, but very charming. People there are helpful and friendly. There is a beautiful castle and a beach in walking distance (where we where completely alone, compare to the other more touristic once!) If you want a place to stay where it's genuine, beautiful nature and great atmosphere you should go here. We will come back as soon as possible!
P.s. the best thing to do: To run along the beach in the morning and walk to the centre and have a morning coffee with the locals. True joy.
