Stayed for Kool Deadwood Nites in 2019. Was reasonably priced, about that of a hotel room.
It is a nice set up, if you have 2-3 couples or a 1-2 couple + older kids. Not a lot of 'play' room for younger kids if cooped up in the winter time. They have a neat little loft with two twin beds and a play area and then an actual bedroom in back part of the loft with two double/queen beds. Master bedroom w/ bath and a separate bedroom on the main floor. There is also a second full bath on the main floor.
Kitchen set up is nice with a bar area (4 stools) and a table (it'd seat 6 comfortably).
Lots of condiments left over which was great for cooking (salt, pepper, etc). We used some and left a couple things we purchased. Several pot and pan sizes, as well as lots of 'extras' that we did not use like a waffle maker, fancy glasses, and several options for plates/bowls. Very small dishwasher that worked pretty well, but we washed most dishes by hand as there were so few. Washer and dryer on site that you can use if you want, which would be great in a pinch or if you were staying longer. We spent our days out and about so not a lot of time at the cabin other then to sleep and eat.
I was very pleased with the cleanliness of the cabin when we arrived. It has a nice deck and location is convenient. Easy to find. If you are familiar with the Terry Peak area it's at the intersection of Buffalo and Last Chance. I would stay again or recommend to a friend.
