The Conde Nast Traveler Hotel Gold List highlights the top hotels in the World. Only 29 hotels were selected in California (these are more rare than Michelin Stars at Restaurants), and Hotel Valencia was the sole Silicon Valley hotel on the list. To put that in perspective, of ALL the hotels in San Francisco only the St. Regis was included on the list.
Other Bay Area hotels that made it were the Ritz-Carlton in Half Moon Bay, Lavender and Vintage Inn in Yountville, Hotel Healdsburg in Sonoma and several in Napa (Auberge du Soleil, Bardessono, Calistoga Ranch, Solage Calistoga).
