A compound of seaside cottages linked together by paths and beautiful landscaping, with breathtaking views of the crashing surf below. Our “room” for 2 was actually a one bedroom one bath cottage with Livingston and kitchen. The pool was adequately sized and gated and locked to prevent inadvertent entry by unaccompanied children. We arrived 2 hours before check in but were given a parking pass and entry to the pool area and use of the grounds. Couldn’t imagine a better place for location and comfort.
