    "Mill Valley is a fabulous place to live - very cozy little town minutes from the Golden Gate bridge and all the city has to offer, but also easy access to all of Marin's charms, including the best aggregation of restaurants in the county, as well as the whole of the Golden Gate National Recreation Area. This town was rated one of the top 5 places to live and one of the best in terms of safety and overall lifestyle in the whole country, and it is indeed that. Shelter Ridge is well-maintained with great neighbors, and I highly recommend it."
