This was such a find! We were traveling and just wanted to have more of a Montana experience rather than a plain hotel and we struck gold with this place. It was beautiful and historical. We loved walking around the breathtaking grounds. We rented the master suite and had a balcony where we sat outside and enjoyed the weather and the beautiful trees. The bed was supreme and the pillows were also very comfortable. The entire room was so delightful. It was awesome to go down the windy staircase and into the dining room and kitchen. It was like our own place, stocked with milk, cereals, coffee, tea and a few snacks. We only stayed one night so we didn’t cook but could have. We played chess downstairs on an old-fashion chess set. We also got a voucher to get breakfast across the street at the breakfast club which was absolutely delicious! I recommend staying here. So clean and kept up well. You will not be disappointed. The hosts, Tayli & Bryson, answer all your questions promptly, and check-in was a breeze.
