My group enjoyed our 8-night stay in this property, which is centrally located in Custer as a great home base for exploring the Black Hills. The host was gracious and accommodating and easy to work with. We had easy access to Custer State Park, Jewel Cave National Monument, Wind Cave National Park, Crazy Horse, and Mount Rushmore each within a 25 minute drive (or less). We also made day trips out to Devil's Tower National Monument and Deadwood, which took longer but were certainly still doable if planned for.
The kitchen was well-stocked, which is something we appreciated as we cooked most of our meals ourselves there on the property. The kids had a great time exploring the grounds and using the trampoline and air hockey table.
For clarification, the layout of the home is a little unorthodox. There is one bedroom in the basement, which being below ground does a good job of staying cool. It is adjacent to a bathroom that was closed for renovation during the time we were there. If access to a third bathroom is important to you, you should seek clarification from the host as to the status of the basement bathroom. The laundry room and the game room/den are also in the basement. On the main floor is where you'll find the master bedroom and bathroom, the kitchen and pantry, the entry hall/coffee service area, the dining room, and the main living room.
The unorthodox layout of the place is mostly about the upstairs floor. There is a bathroom at the top of the landing, and on either side of that is a bedroom that is open loft style, meaning that the upstairs bedrooms each have one upper wall that opens up onto the living room below. While each of these loft bedrooms have their own doors that can be closed on the second floor landing, they will always be part of the space shared with the lights and sounds of the main living area and kitchen. You may wish to take this arrangement under consideration if your group doesn't intend to all go to bed around the same time. As for my group, it didn't matter very much and we adapted to the situation without any problems.
The deck outside was spacious and we were treated to some spectacular sunsets and lovely views of the night sky. At times, the nearby highway was a sound nuisance, but it would not be enough to dissuade us from staying here again (we weren't here during the motorcycle rally in Sturgis however, if that changes your calculus).
We would definitely consider staying here again.
