We spent the night here with friends from out of the country as a quick getaway. We arrived with no expectations other than a very nice dinner, so it was an extremely pleasant surprise to find a resort that was as well run as this place. Service was truly impeccable - probably the best we've experienced in this country (and we've stayed at many nice places in the U.S. as well as in Europe and Asia). If we had to give specifics, they'd be little things -- spa masseuse who spent an extra ten minutes with me, barman who only charged me for a small bottle of Pellegrino for a large one because he had run out of the former, etc.. . But as a total package, it's extremely rare to find this level of service without the attitude.
Restaurant was also amazing. Every dish was perfect and beautiful and the wine pairings delicious. Probably the best meal we've had in the Bay Area ever (including the French Laundry). They're doing something very special here.
Only caveat is that the rooms were a tad small without much of a view.
