My sisters and I stayed for a week and it was a wonderful home for our vacation. We loved the property and area so much, on the day we left, we booked the larger home for next summer so we could bring our dad.
Cooke city is a wonderful town and was part of our decision to book for next summer. So very close to Lamar Valley.
Communication from the owners when we had a question/request was very prompt and easy (and later in the night due to our late arrival).
The creek, hot tub, and sauna made for wonderful, relaxing mornings and evenings. The families staying in the larger home next door had campfires by the creek each evening (there was a fire pit by the creek). Although the units are close to each other and the laundry room/sauna/hot tub are shared, there was never an issue. They have 2 large washing machines and dryers.
Definitely do your grocery shopping before arriving, but, there is a general store in Cooke City that has almost everything you would need in an emergency (not a lot of variety but will get you through if in a pinch--we were surprised by all they had to offer).
The kitchen has all you need to cook meals and the beds are VERY comfortable.
The property had a bison show up almost each evening. A local said he's been around for years. We saw 4 moose just down the trail.
This really is a special place. We've stayed in Big Sky and Gardiner for over 10 year trying to find a place we love and we've now found it with this property and city.
