Angelo and Cristina has a really beautiful farm, looking directly on Mount Etna. They have just built their own house, as well as a separate guest house from wood (I guess it is made of wood, though I'm not an expert in building), with an own bathroom. The guest house is very nicely furnished, and surprisingly cool compared to the hot weather outside. There is also a nice terrace, with a view to the farm & Mount Etna.
Angelo and Cristina was very welcoming, recommended really beautiful places to visit in the neighbourhood, and Angelo patiently explained to us how to get to the top of Mount Etna.
Many thanks for the 2 days we spent there, I would recommend to anyone to go and stay at the Eco Farm near Piedimonte Etneo.
