We (a Dutch couple that loves nature & hiking) had a brilliant stay in Casa Francesca. The location was perfect for us, close to some beautiful nature areas and not far from the highway as well, if you want to visit Catania or other cultural spots. Castiglione is a nice little town on a steep hill with old medieval allyways, some nice bars and restaurants, and splendid views from the old historical centre on top of the village.
Vincenzo and his family were most welcoming, very committed and very friendly. They waited for us outside upon our arrival, showed us where to park and showed everything in the appartment, where Vincenzo had left some nice food as a welcoming gift. He also kept in touch in a nice, polite manner thoughout our stay to make sure we were allright.
The appartment itself is small but very caracteristic, it has 3 floors and steep stairs (so you'll stay in shape, climbing the stairs everytime you go to the bathroom ;) ) and we thought it was great. It is very fresh and clean, the bed is large and comfortable, it has all kinds of equipment you would need, and last but not least: it has possibly the greatest view on the majestic Etna of Castiglione, from all rooms but especially from the lovely, spacious roof terrace.
