As one of Alex my son's family group, I agree 100% with his review. Our hosts were very helpful. Their villa is well situated for exploring Southern Tuscany and Umbria.
I could not recommend Villa Il Giardino di Diana enough. The house itself is lovely, nice and cool inside even in the heat of the day with lots of big airy rooms and all the equipment a family could need. The grounds are beautiful, lovely flowers, various dining and sitting spaces to find peace and a great swimming pool for the kids. The extra equipment kept the big and small kids happy - a great outdoor bbq space - and table tennis, table football and swings. It's in a great location to reach most of Tuscany. We came for my father's 80th and it was perfect.
