Satnav got us a bit lost on the way in - the Sgaravatti factory is a good landmark, be sure to turn left immediately after it. But once we knew where it was it turned out to be in quite a convenient location for getting onto main routes and visiting various nearby restaurants/towns (for eating there's a trattoria just down the road that was lovely and friendly, Martini by the DPiu supermarket on the roundabout into Montevarchi was cheap and did good pizza; supermarket-wise, the Coop Fi in Montevarchi is much bigger and better than in Levane).
Rooms were large, outdoor table in the shade was nice for breakfast, and there was plenty of outdoor space for 1 year old to toddle, with the highlight being the nice cool pool, which was a nice size as well as having a shallow section perfect for kids.
The one negative was the lack of supplies in the apartment - we had to buy a coffee pot (there wasn't even a kettle), tea towel and washing up sponge, as well as disposables like hand soap, kitchen roll and bin bags. Suffice to say we've left it better supplied than we found it.
Overall I would go back, and would particularly recommend this apartment to families with multiple children - the second room had beds on 3 levels that I'm sure they'd love, and with the pool, grounds and activities (ping pong table and volleyball net) there's plenty to keep them busy.
