The only minus that spoiled the whole impression was the apartment. Via booking.com we ordered 30 square metres apt, but get hardly 17 called "Mimosa" with 3 narrow windows, 2 sq m kitchen place and dinner-table opposite the entrance door. We thought that's not important 'cause we were going to spare a little time there. But the apt occured very wet and dusty (and I'm allergic). Well, I think it's not fair to set the same price to such a different apts. The water was poor, don't envy you, if you've long hair. Wi-fi signal is good near reception and restaurant, not in the apts.
Wonderful place, nature is astonishing. The territory is organized very smart and nice with tables, chairs and deck-chairs, hammock, swimming-pool. The food is very tasty, dinners are very rich. The place is very good to stay and visit Montepulciano, Montalcino and Pienza. Val D'Orcia is breathtaking.
