Wow! We have rented these kind of properties in the past, and this was the best EVER!!! We had 3 adults and 5 kids, and it was perfect for our family.
First of all, and most importantly, the kitchen was stocked! They had everything we needed, and in some cases, doubles and triplicates. The only thing we needed was a crock pot, but tons of pots, pans, dishes, wine glasses, paper towels, knives, dishwashing liquid and detergent.
Also, plenty of toilet paper and towels, but bring your own kleenex. There is an ice maker and a washer and dryer, bring your detergent. The hot tub rocks, and stayed pretty hot, even though it was in the 30's outside. One shower/tub had jets, but we just used the hot tub because it was so nice.
Tons of balconies with rockers, a picnic table, and a charcoal grill, with utensils!!! There was a vacuum and a broom. Bring beach towels and towels for the kitchen. And fyi, the upstairs gets way hotter than the downstairs. They were freezing down there, so if coming in the winter, bring blankets, lol.
Seriously, this was the best rental we've ever had!! Only complaints were minor, and include super hard bed in master upstairs, and drive was tricky, as it was gravel and full of big pot holes. But we were super happy with our stay!!!
