We stayed here as a group of 2 families in late May/early June. The villa is great. It's not as remote as it might appear from the pictures as it's on the edge of the hamlet of Iano, only 200 metres from the shop and two restaurants. However, the villa and grounds are very private and not overlooked at all. Iano is about an hour from Pisa and Florence. San Gimignano is about 30 minutes away. The rooms are high-ceilinged, spacious and tastefully decorated. The grounds are really well-maintained with lots of places to lay or sit in order to catch the best of the sun. The pool is lovely (a little cold when we visited), although not overly deep at any point, so careful if you dive in! Our weather was good. Mostly sunny intervals with one day of thunderstorms during the middle of the day. There were plenty of mosquitoes active in the late afternoon to evening so bring some repellent. The local shop is well-stocked and Ristorante-Pizzeria Antico Borgo is a great place to eat. If you want to sit over the road with the nice views it's advisable to book a table earlier in the day.
A few minor quibbles. Firstly, as described in the villa details there is a non-negotiable 150 Euro cleaning charge to be paid in cash. To my mind, any cleaning should be part of the rental price and not something added on in cash (is this to avoid tax or tripadvisor commission?). The wi-fi signal is strong, but there's not much coming down the pipe. I wanted to watch the Champions League final, but no chance of that, just buffering. Also, the wi-fi requires you to keep signing in with individual usernames which is a bit of a pain in the backside. Lastly, and I realise that this is a moot point with rental properties, there were no non-perishable ingredients at all in the villa. Not even salt and pepper. If you're flying in and therefore limited in how much baggage you can take, you can expect a hefty shopping bill when you stock up.
