10/10 Excellent
"Decent Mini golf and restaurant/bar on property and free kayaking across the bay full of nature like a nursery for all the upcoming sealife families, superior water quality and views. Not to mention the pool and the rental boats for exploring the islands and restaurants, a real hidden gem and a piece of paradise..."
