We had 16 people from 5 separate family groups. The space inside the house was ample and allowed the young adults to hang out on one floor and the older adults to be on another. Large seating areas for meals, lounging, game playing and puzzles. The extra refrigerator, dishwasher and ovens were much appreciated to make meals.
There was a coffee pot and a Keurig. The microwave at knee level was a bit of challenge but we adapted. There were plenty of plates, cups and utensils. However, please note there are no spices, oils, salt and pepper of any kind. Most places we have stayed at least have some spices but there was nothing.
We used the hot tub and it was clean. Having private bathrooms for most of us was an added benefit and those were also clean. It was noted in another review that there was a leak at one point and it's still on the ceiling of one of the bathrooms. Pool table and wet bar (with yet another refrigerator and dishwasher) was also used. Easy access to the beach across the street. We loved having so many porches to sit on (even in the cold) to watch sunrises and sunsets. Our key benchmarks are cleanliness, space for everyone with as many private bathrooms as possible, linens provided, and furniture that doesn't look worn. Amazing Grace met all of them. I would suggest felt on the bottom of the chairs so it doesn't scratch the floors!
