Irene's home is very nice and Castelmola is a beautiful medieval town. However, if you are interested in Taormina, Castelmola is remote. You can walk down the mountain which takes about a half hour or drive down winding mountain roads. Castelmola would be a great day trip from Taormina and you can take the bus. I can imagine that it is quite wonderful to stay here during the hot summer months in Taormina.
