The place was really great. It's perfectly central and in the heart of the old town. But it was still not too loud to sleep.
The bedrooms were beautiful and really comfortable. The room etna is a little bit better than room mare but you will have a great experience on both rooms.
The kitchen is a bit small and the ceiling is really low (185cm I guess) but it has everything you need. I recommend to eat outside either way because of the great Sicilian cuisine.
The terrace is the heart piece of the house. It's big and you have a great view from it. You can even see the etna from it.
Sebastiano is really helpful and can give you tips what to visit. He is also always available and will help you if you have some questions.
All in all a perfect stay.
