We had a lovely week-long holiday in September. The house was in perfect condition. The children slept on the top story, and we were on the ground floor . The proprietors were very friendly and lived on site . There was a kayak also made available to use
The snorkelling is a very good high tide snorkel (if you don't mind sea snakes) and on the low tide you can walk over to a nearby Island.
You do need a rental car, although there is a small general store a short walk away. We really enjoyed our holiday overall.
