Maria is the best host ever. Really. She is one of the very few people who make you see why staying abroad with airbnb is such a good idea. Maria took us hiking on Etna - on the trail and off the trail! Her knowledge of history and nature is enormous. She knows all the facts, shows you all the sights, and can even take you to see a volcano eruption if it's happening when you're there! She should be a tourist guide and do sightseeing tours for a living! The apartment is also really nice and cosy: a self-contained flat in the centre of a beautiful town with great old churches and market square which gets filled up with locals in the evening. Great pizza place on the same street; best Arancini (and some top 3 gelato) in Sicily on the market square. Trecastagni is worth staying 3 nights, but hiking on Etna with Maria is worth staying a month!
