Earlier this year we decided to make the detour to Yountville for a Thomas Keller pilgrimage. We chose the Villagio upon French Laundry's recommendation. Prior to our arrival I had much email correspondence with the concierge Mary who was very helpful in getting us reservations at the restaurants we wanted.
The resort has excellent facilities - manicured landscaping, a lovely pool area, afternoon tea daily in the lobby and lovely lemonade available at any time. The rooms are comfortable and spacious - they are looking slightly dated but have been well maintained. There is free WiFi, which all hotels should offer nowadays - and the speed was good.
We didn't have any meals here, but many of the guests did and from a distance they looked good. The staff were attentive, friendly and efficient. I would return.
