I stayed at Gaetano's place for four nights on my own. It was a bit to big for me (I didn't realize it from the photos that it's a two story building) but I think it would be great for a couple with or without kids. The apartment has two terraces and lies at the main road up the hill which can be a bit loud at night from cars passing by.
I was picked from the train station by the women who manages the house which was really kind of her and she gave me a quick tour of the house and showed me how to get to Taormina. There are steps up and down the hill. It takes about 10-15 Minutes to get to Taormina and back but you should be fairly fit to get back up the hill :)
