    "I've lived here for 2 years and enjoy the walkability to local theatres and restaurants. There's a strong homeless contingency that detracts from the seaport. But you can't blame them for wanting to be in paradise."

    "We vacationed here for the month of February 2014. We did not rent a car but had bikes for a week. We are walkers and walked an average of 1-2 miles for dinner and many miles during the day touring, hiking, etc. This area is accessible to most anything."
