Calcicera Alta is a magical house in a lovely area outside of Noto.
You should be aware that the house is very secluded. Google maps have a pin, but the map on my iPhone couldn’t find it. I would recommend doing a large shopping on arrival because the markets are a bit far, and taking out the trash is also a bit of an exercise. But, if you are prepared and plan accordingly - it shouldn’t be a big deal.
I would also strongly recommend having their chef prepare a meal one night of a stay. We had a vegetarian menu and I think it was the best meal of our vacation.
Overall, it was the right choice for us, and we had a wonderful time.
