Santa Rosa's Vintners Inn, located quite close to the Charles M Schulz Sonoma County Airport, is a delightful yet low-key luxury hotel. This was a quick trip and we didn't have an opportunity to patronize the restaurant or the cocktail lounge; we'll have to leave that for our next trip.
Our room was spacious, spotless, and well-appointed. The king-sized bed was very, very comfortable. Many years ago I was an executive with Sheraton Corporation; Vintners Inn is the equal of any of the dozen or so hotels I encountered way back then.
If business or pleasure (or both) take you to central Sonoma County, I'd recommend Vintners Inn in a heartbeat.
