Cabin 5 at Robins Roost was awesome, and the owners of the property for the last 7 years are amazing! This cabin is the only one I believe that is as updated and modern as it was. Very cute, clean, with amazing fireplace, "mini-split" heater and a/c in main room. All of the other rooms, they said were "cove heat" and each room had its own thermostat, which was great because we enjoy our bedroom cool (we stayed in April and were able to open our windows, which was SO NICE!) but bathroom warm. This cabin has 2 bedroom and they are on opposite sides of the main room, which is nice for a little extra privacy if traveling with others (or a for a break one night from a snoring hubby!) The owners thought of almost everything when updating this cabin, and I highly recommend it!
Just know that it IS a cabin more than a typical vrbo, so there are very few "added amenities". There are no condiments in fridge (but there is an amazing local grocery store called Krull's just inside Hill City, or bring groceries from Rapid City or your home. There are no little shampoo or soap bottles, no hair dryer or iron, etc. I also do not know how a person would plug in an electric car, especially with the small, awkward parking spot for this cabin (cannot have more than one vehicle parked up at this cabin, nor would a camper or trailer of UTV's fit near the trailer -- the owners MAY have an alternative spot you can park those, however- i would contact owner before considering any of these items.)
