Meritage Resort and Spa
875 Bordeaux Way, Napa
Given its grand amenities–including its own nine-acre vineyard–this hotel and spa is definitely more of a resort, therefore not the best bet if you're looking for a quaint-style inn or hotel. The customer service is excellent, as is the spa. It offers tastings in it's cellars and is only about a ten-minute drive from downtown Napa if you're looking to explore or head out to dinner.
Carneros Resort & Spa
4048 Sonoma Hwy., Napa
Formerly the Carneros Inn, the 28-acre resort is now under new ownership but still maintains its farmhouse-style charm, with a few welcome updates. Like many Napa hotels, rooms here are situated in individual cottages, each outfitted with rocking chairs and an outdoor shower and fire pit. An adults-only pool overlooking the neighboring vineyard is probably the most Instagrammed thing on property, but it's totally idyllic all the same.
