Elio and Sonia are very kind hosts. They'll check in with you regularly to see if you need something and will give you tips on the beautiful National Park. Communication is great, although it helps if you speak Italian. Sonia can speak English though, so she will be of help in that departement.
The place itself is clean and spacious. The only thing we would change is the bed, which to us felt a bit uncomfortable and not well suited for tall sleepers.
The rest is top notch, so we can definitely recommend this place and it's great hosts. They'll welcome you with open arms.
