Alessandro's house is in a beautiful location that is truly what the dream of being in Tuscany is. Sitting up on the third floor veranda overlooking the valley is just the perfect way to start or end your day. The space is very comfortable, and reminds me of staying at my grandparents place in the country.
Have a car, preferably one with good ground clearance. You are on top of a hill over Florence, so while it is not far, a car is certainly ideal. The kitchen is well equipped, though we did not use it for much.
Alex and Veronica are very nice, and they live on property so they are easy to get ahold of if you need anything at all. We can't wait to go back.
