It is much more beautiful than the pictures show.
This is my main impression to share: usually places are never quite as nice as the pictures suggest. Angelo e Cristina's place is way more than the pictures show. It is a sublimely peaceful and beautiful environment to stay in.
The house and land around it have been created and looked after with a lot of love and creativity and the atmosphere is very special.
Having that view and presence of Mount Etna is something that has to be experienced - it cannot be well put into words. It (she - you'll get it when you're there) is a powerful and wonderful presence.
Go stay here. It's gorgeous.
