We are really happy with this accomodation. It was perfect for us 4 adults and 1 infant (aged 20 months), with a spacy rooms, a large beautiful garden and a nice pool. The host couple is very welcoming, friendly and helpful.
We stayed for 7 days and our electricity bill was €18. We were there in May though and didn't need to use the air conditioner at all, which might've saved us a few euros.
We had a rental car which might be a necessity since the house is located in the outskirt of Fontane Bianche.
