Maybe 3.5 stars. The environment is gorgeous and serene. Nice place to get away from daily life and relax. There are some nice places to eat around there too.
That being said, I don't know what else you might do there. I'm not sure how those retail shops even stay in business, selling what they do. The farmer's market that goes on there on Saturdays is very expensive. But if you've never been here, then definitely try it out. Find your zen.
