We really enjoyed our stay at Arrigo. The rooms are very comfortable and clean. The well maintained garden with the swimming pool are great and comfortable even when more guests arrive. The kitchenette is tiny but was enough to cook a simple, small meal, make your own coffee or drinks.
The breakfast included in the price is in the nearby hotel - Villa Neri and is a real highlight of this place - it's an extensive 5 star hotel type buffet in a beautiful garden setting.
Arrigo is great if you want to explore the Etna area - go up the mountain or go to nearby towns.
