We had 3 adults, a 13, 9 and 7 year old. We didn't feel cramped in the house at all. We feel the homeowner utilized their furnishings with space well.
Everyone slept comfortably at night. It rained for an hour each day we were there but there were plenty of games on hand to keep everyone occupied.
Kitchen was well stocked with utensils and cookware. We did run to the dollar store to get foil, toilet paper and paper towels. So when packing, keep some of those essentials in mind to pack. But the dollar store isn't far away if you need something.
We didn't have much luck fishing or crabbing. We caught 4 crabs in the traps over 3 days. Lots of croaker and hardheads were caught. The deck space was nice and accommodated us all while fishing. It was nice at night to see the fish in the lights. I would also recommend bringing your own lawn chairs for out there.
Overall, we had a lot of fun and enjoyed a comfortable stay. Thanks for having us!
