Staying in Antonio's house was fantastic, we stayed with 2 kids after checking with Antonio (7 and 10). The steps weren't a problem for us at all but it was good to be prepared, the pool was lovely, the views are truly amazing.
Hiring a car and parking on the street below is not a problem, there may be a little wait for a space but we were always OK (and stayed in peak season). It was good to be able to get to the supermarket and up to the villages above Taormina. I think it was about 45 mins from the airport so not a big journey at all.. the tolls from the airport were minimal (€2 or so).
The beaches that are within walkable distance are nice. The restaurants nearby are also lovely, we liked Ristorante Castelluccio and eating in the garden. Staying around the house and sunbathing and using the pool was really chilled out too.
Antonio is a warm, generous and welcoming host, the reviews hopefully all confirm this. We really enjoyed our stay and I would recommend Antonio's house to anyone considering staying near Taormina. Thanks Antonio.
