I've visited Sonoma every Feb for the past three years, and stayed at this hotel every time. The location near the square is excellent, and rooms spacious, and the individual balconies overlooking the courtyard are a great place to enjoy a glass of wine after a day touring the sonoma valley. The breakfast is ok, but given the dining options available around the square, I would give it a pass unless you are in a hurry or a budget. The fireplaces are a bit gimmicky, as they only burn duraflame logs, and only one at a time - its not really the roaring, crackling fire one imagines.
Be aware that this two story hotel does NOT have an elevator.
