We recently stayed at this property with two families, totaling nine people with kids ranging in age from 13 to 20. Overall, we had a fantastic time and loved the house, especially the rec room and jacuzzi, which were big hits with everyone.
However, there are a couple of things to note for future guests. The property is listed to sleep 12, but that count includes a pull-out couch, which is suitable for small children but might be uncomfortable for adults.
Our main issue was with the hot water situation. After just two showers, the water would turn very cold, which made it difficult to get ready efficiently, especially after a long day of hiking in Yellowstone. With everyone needing to shower before bed, we found ourselves having to wait about an hour between every two showers for the water to heat up again. While we managed, it was a bit frustrating, and I would recommend upgrading to a tankless hot water system if the house is being marketed for 12 guests.
Despite this, the property itself is great and in a fairly quiet neighborhood. It’s also in close proximity to the West Entrance of Yellowstone, which was very convenient. Overall, I would highly recommend this property, just be aware of the hot water limitations if you're planning on having a full house.
