Nice location & beach. The only market/deli/restaurant are owned by the hotel & nothing else within walking distance. The toilet was lose with a loud annoying clank each time it was used. No working ice machine, but we could walk to the bar or convenience store for ice. No heat in our room, which would have been nice one the evening got chilly.
