We went there to see their spa, as it is well-known fir high standards, we weren't disappointed by the quality of the treatments.
The hotel is beautiful, the rooms are large and well-decorated in tuscan style, we were a little bit disappointed by the very small window with no view.
The service staff is kind, but in a "leading hotel of the world", you could expect to be asked if you want something to drink, when you are sitting on the terrace near the restaurant. Obviously there was no possibility to be served a pre-dinner drink there, although there were 5 persons of the staff, standing there and chatting...
Another thing that we did not appreciate, was that the lady at the front desk, was not able to inform us about where we could find a nice village to visit. She gave us the copy of a map (which was very unprecise) without further explanation, although we talk italian fluently. You could see that she didn't want to be helpful. We managed to find something without her help, but in that kind of hotel you could expect a better service.
