Don't be discouraged by the size of the apartment, it has everything you need. We enjoyed our stay. Tonino is friendly, responsive and helpful. Small minus is that location is further from historic city center (cathedral), google says 30 minutes walking, but there are also restaurants and shops around, plus you have free parking in front of the house and better starting point for trips to Etna and Taormina.
Overall I would recommend Tonino's apartment :)
