This is a nice little studio just about a 7 min drive from the West entrance of the YNP. It was very clean and comfortable and Mari, our host was super responsive. The check-in/location instructions were very detailed but we did have a little bit of trouble finding the place since the street is an unmarked dirt road. We loved the stain-glass door and the pretty flowers at the entrance.
There is a steep stairway to the second floor, so moving luggage can be an issue. There is a portable air-conditioner but we found it quite noisy and it kept stopping and starting, it would be good to also provide a fan. The shower is tiny, more like a cruise ship shower. If you can deal with these small drawbacks, this is a lovely place for two people for your Yellowstone vacation.
