The owners of Napa Valley’s Hall Wines in St. Helena and Rutherford took over this former bed-and-breakfast just south of Yountville in 2006, gradually transforming it into one of the most sophisticated boutique hotels in Napa. Today its 43 rooms are spread over five buildings on two acres, featuring gas fireplaces, heated bathroom floors, Nespresso coffee makers and other luxurious amenities. Book the Senza Loft and adjacent Senza suite for a two-bedroom, three-bath spread with a sofa bed in the living room and a professional-grade kitchen.
