Great Host! Maria Teresa is simply lovely and has a great heart.
You would be staying at the main street of Acireale in a stylish Italian flat just next to a lovely church that everyone wants to take a photo of and at #66 there is a local cafe with great coffee and candela siciliana where you can have your breakfast. It is also a good starting point for visiting Volcano Etna. I did it with vivoetna as the guide is from Acireale and picked me up from the place and loved the experience! You can pick up more options in the tourist information. For me Acireale was also a good starting point for visiting Sicily by car. You can also enjoy the beach, but careful as this part of the seaside is stony (thanks to Etna) and Acireale is sitting on a lava terrace overlooking the sea, so you need to get down to the beach (and the train station if you have no car). If you are lucky, maybe Maria Teresa will give you a ride and you will enjoy then your Italian Vespa experience :)
