The house was plenty big for our 2 families with a lot of kids. The location was perfect for us, and the children loved having easy access to the beach. There were plenty of "toys" that come with the house to keep everyone entertained (like sand toys and kayaks).
The house itself is immaculate, very nice, clean, and welcoming. It already included many of the basic items that we needed for the week (like beach towels)
We managed to rent a golf cart from the nearby resort which wasn't necessary, but came in handy when we needed to go the nearby ice cream shop, or to a different part of the beach on the island (the island has one restaurant and ice cream shop at a nearby resort).
Leaving and coming back to the island for a day trip does cost a bit of money since you have to take the ferry back and forth and purchase a pass, but this wasn't a problem for us and the laid back vacation we were looking for. The refrigerator was plenty big enough to allow us to stock food for the whole week.
The island's beach itself has tons of seashells and shark's teeth. It's very much a low traffic area, and we rarely saw more than a dozen other people on the beach at any one time.
The owner of the house was also great to work with and always very responsive.
If you are looking for a laid back vacation, and just want to spend some time on a nice beach in a nice house, then this is for you.
