Carol and Jim live in Rapid City which is such a great place to base yourself. Mount Rushmore, Crazy Horse Memorial, Blackhills, Badlands, Deadwood, Speafish, and a huge number of attractions are easily accessible. Even Devil's Tower is not far away. It is a super location.
Carol and Jim are just the nicest couple in North America I am sure. Carol is very talkative and she is full of information, advice and tips. She will do anything to help you out and make your stay as comfortable and as interesting as she can. Jim is the quiet one, but don't let that fool you; he is a thoughtful man who gives his opinion in a considered, valued way that is based on his considerable experiences in varied fields. He is a very interesting man and I would have liked to get to know him more. These two people are gems in the Airbnb world.
Thinking of the above it goes without saying that the accommodation is as described; it is comfortable, in a good location and spotless.
