Overall: pleasant experience in May, good cleanliness (though old), enjoyable if you like being alone.
Probably better experience during the summer (when there's actually someone in the property, that the pool is open and that there are degustations).
Rooms/apartment: beautiful estate, globally clean and very spatious.
Fully equipped apartments (fully equipped kitchen, towels provided, but no soap/shower gel/dish soap/sponge).
We had to turn on the water heating ourselves (when discovering a cold shower).
Also old and with occasional insect encounters.
Service: almost none. Alberto was friendly and welcoming upon arrival, but spoke only italian and had no idea what was up with the reservation (didn't know we were coming).
We were looking forward to being in the vineyard and tasting the products of the farm (promised degustation upon arrival) but ended up being alone during the whole stay. No reception, noone to call if there's a problem. We had to find where to pay upon leaving (they accept credit/debit cards).
No internet/wifi. Pool not yet open in May.
Place: remote location up in the hills (car needed to move around). Final access road (~50m) is made of rocks and in pretty bad shape.
40mn away from Florence.
Very good restaurants around.
