This was our first trip to the Old Mission Peninsula, and Tesoro proved to be a wonderful home base for us, right in the middle of wine country. The accommodations and our hosts, Les and Jane, were warm and inviting. Les's breakfasts were absolutely delicious--and we delighted in dessert each evening after turn-down service. What separates outstanding B&Bs from the rest is the attention to detail and level of care for the guests. Tesoro is certainly in this class. If we return to the area someday--and I hope we will as our weekend couldn't have been better (perfect weather and some of the most beautiful scenery in the Midwest), Tesoro is first on our list.
