We selected to stay 3 nights at Livernano, based on the great reviews on Trip Advisor.
Livernano was as described, but we found it a bit limiting at nights. It is some 8 miles along gravel roads to reach Livernano from the main roads and there is no lighting on these gravel roads, so we had to be in there before nightfall - which was about 7:15 pm each evening and we could not go to the nearby towns for an evening meal. Also, the first day we had trouble finding the place because the "brown sign" that we were looking out for was in fact a small white sign and we missed it.
That said Livernano is beautiful. The grounds are very attractively landscaped and there are lots of flowers and trees. Small tables and chairs are set out around the buildings and pool so that you can sit and enjoy the Tuscan landscape with the vineyards, etc in the sunshine during the day. In the early mornings, there were also rolling mists on the hillsides which made it look fantastic. And we visited the owner's vineyard nearby and sampled some of their fine wines.
The accommodations are also beautiful. We were two couples and we each had a standard villa room, which was spacious and well furnished - just as they look on the website. The beds were extremely comfortable.
The breakfasts were wonderful with lots of choices of things to eat and drink, and you could also get a tea or coffee in the early morning to take back to your room.
In the evenings there were several fixed menu courses to choose from. Often we selected 2 or 3 several of the 4 courses each, and then shared them (including the dessert course). The food was fantastic, but it would have been difficult to eat all 4 courses each day.
Daniela, who runs the place, was incredible. She answered all of our questions each day and helped us to plan our travels in the surrounding area, including visiting several Tuscan hill towns South and East of Siena.
All in all, we had a great time. However, Livernano is best you want to stay there for say 3 days to celebrate an anniversary or have a long weekend away. We had hoped to have dinner at some of the smaller towns nearby in the evenings and this was virtually impossible to do due to the roads.
