Absolutely stunning. Beautiful scenery, right on the owners' property, so we got to see their vegetable farm as well as their animals. We spoke mostly in Italian, but it seems that they do just fine with other English-speaking guests. We opted to order a homemade dinner from them, 15-20 euros per person, filled with pasta, sausage (optional), an array of vegetables, homemade wine...it was absolutely fantastic. It made the night before heading to the Rome airport stupendous.
One double/queen bed in a private room, and three single beds in the main living room (that double as couches). We were two couples and it worked out great.
One thing: it was surprisingly loud during the night, mostly from animals outside. The windows had to remain open (with mosquito-proof screen doors of course) to let cool air flow in since there was no fan or air conditioning, so I used headphones while I slept. I am also not the heaviest sleeper, so you may sleep just fine throughout the night.
