We stayed for Spring Break 2019, with 12 people from three families. Since the house is new construction, it is very nice and clean. The rooms are big, the decks and pool are nice, and the amenities are what you would expect from a new house. The location of the house is perfect for getting to the beach, and the bikes available are a huge plus.
Only issues we had were the Wi-Fi connection, which was very spotty - we had to reboot the router several times each day. This gave us a good excuse to keep the kids outside, though! The rental company said they would look to get that replaced when we left. Other than that, the kitchen could have a few more cooking bowls and service dishes. We cooked a lot of big meals, and sometimes we had to get creative in the cooking and serving process. Only other recommendation is changing out the deck rail slats with see-through slats. The deck rails were pretty much solid, so if you sat in the deck chairs, you could not see much if you are short!
Other than those very minor issues, this was a wonderful stay in a wonderful spot. I highly recommend it to large groups like ours.
