We stayed 7 nights in a 1 bedroom apartment and had a great time.
The property is truly beautiful, exactly what we were envisaging in Tuscany. They make wine and olive oil on-site.
The apartment was comfortable and very clean. Sure it is a bit aged and rustic, but again perfectly clean and functional. WiFi, hot water, appliances, everything worked just fine.
In a way, what you lose in modernity and perhaps comfort, you gain in charm and atmosphere which to us was not a problem, au contraire. Especially as the price was very reasonable.
We haven't tried breakfast. Restaurant was good although nothing to rave about.
Staff was very friendly and helpful.
Only thing that bothered us a bit is that none of the essential supplies are provided except toilet paper (2 rolls) . You have to buy dishwashing detergent, oil, café and such which is inconvenient (shop is 20min drive away) and at the end we wasted what was not used.
Overall, excellent relaxing week and we wished we booked for longer.
