We stayed at this holiday house in July with two families, 7 people total. It is a lovely rustic Tuscan home located in a quiet little valley about 10 min from Montopoli.
Pros:
Awesome pool - it was huge, clean and with lots of good seating and umbrellas around the pool. We spent many many hours in it, since we were there in the middle of a heatwave.
Great location - you can get to loads of places in under an hour: Pisa, Volterra, St Gimingnano, Lucca, Florence.
Large house - there was tons of room for 7 of us. 5 big bedrooms, most with a bathroom attached, and a huge lounge / dining room. Lovely lovely outdoor eating space with large table and loads of chairs.
Great oven and stove top for cooking all the wonderful local produce.
Cons:
Beds weren't the most comfortable, but adequate.
In the heatwave two of the upstairs bedrooms stayed quite hot through the night even with fans going. But it was extremely hot.
Overall I'd definitely recommend this place to stay. We had a lovely week there.
