I visited with my adult family and we spent a week here. The house really was perfect for our trip. People came and went, but at one point we had 10 people there, and we all lived and slept comfortably. The bedrooms are all spacious and the layout allowed people to either socialize or have downtime without issue.
The kitchen was very well stocked (happy to report there are PLENTY of forks now!) and adequate for 10 people's food, as well as cooking meals in, which we did almost every night. There was a shortage of hand towels in the kitchen, and no cleaning sponges, so maybe bring those with you.
My one suggestion: We unfortunately had several days of rain while we were there, but the only entertainment was two decks of cards. It would have been nice to have some board games available. Additionally, with the wooden Adirondack chairs on the patio, they were pretty saturated the whole time. Plastic would almost be better so we could have wiped them off.
Other than that, we really didn't want for anything the whole time. I highly recommend this house, both for its interior layout as well as its location - close enough to downtown Folly to walk or bike ride easily, but far enough away to have a very secluded beach experience.
