We had a family group of 9: myself (grandfather celebrating his 80th), 2 children and spouses (4), grandchildren (3), and my sister, age 73.
This was a perfect house for us, clean, well provided, wonderfully situated, private.
We used the house as a base for trips into the Park and a place we could all relax after a long day. We used most of the features, including hot tub, outside grill, TV, appliances, etc.
Owner was very responsive, especially when our battery-operated front door lock had problems. That was quickly fixed. Our thanks to him for providing us a great place to celebrate.
