I travel many times to Italy a year and I stayed and ate at many agriturismi but this was for sure the worst place of all. But let's start with something positive: the landscape is very beautiful and you can overlook the Vale D'Orcia. I was not as a tourist at this form but I did WWOOF (willing workers on organic farms). Be careful wwoofers! Never go there! They do not treat you like a human being...they are not interested in you as a person. You are for them just someone who works for them without having you to pay for your efforts. I did non work 6 hours (like recommended for a wwoofer) but 12 hours! a day. So I did not have to time to visit the area around the farm... The owners and their sons are not unfriendly but you do just not exist for them. you have to work and to shut up, that's all. You also have to sleep outside in a caravan without any heating and this also in the winter!!!! The food was horrible, too - very simple and not enough, so most of the time you had to go to bed hungry.
I ate at many others farms in Italy and this food was the most horrible I every ate!
So I can just advice you not to go there! The marketing for their farm on their homepage and on facebook is very well done but it's not the reality!!!
