Vulcano is lovely. I spent 8 nights with my family (4 people). The house is clearly supposed to host young people ready to get along with the many discomforts the house unfortunately offer, including, and not only, the poor quality of the sleeping solutions, and very old and smelly bath towels. Not for families (!!), not for more than 2 people (!!).
Be ready to buy almost everything can be considered consumable (soap, sponges, oil, salt, sugar, toilet paper). The outdoor space is the only nice place of the house (be ready to be assaulted by flies and mosquitos), although the pictures are representing a very old reality. The garden is neglected, and a lot of useless tools/utensils have been collected in the time and saved in every drawer or closet. The house is messy, and a poor management made of this experience more less than we expected and paid for.
