Heart of Buffalo

Clean and comfortable rooms in the middle of town. Within walking distance of good saloons, restaurants and shops. The breakfast was fantastic. Also close to major highways for people passing through.

Great, clean, affordable.

We spent the day driving from Glacier NP to Buffalo, so a nice room was appreciated. Buffalo is a nice town, so explore the downtown. We stayed in Ella's room, which is next to the street and had one window open, so be aware of this if you are sensitive to traffic noise.

The Historic Mansion House is a very nice bed & breakfast , well situated in the center of the city . But itvs very noisy because you are on main street and the windows let all the noise enter in the room and the air conditionned is also noisy. The breakfast is correct

A terrific town, a wonderful B&B

Most enjoyable, two blocks to the center of town where there are several really nice, independent shops and museums. Rooms are very clean and decorated with western antiques. Breakfast, while not huge is truly home made quality! All in all a wonderful experience!

My wife and I stayed here during our recent trip to Yellowstone. Buffalo is a great western town with character and sites reminding us of true western lifestyle. The Mansion House Inn fit right in with great character and charm. The room was great, beds comfortable, and conditions were in keeping with the best kept hotels. The air conditioning struggled to keep up with the 90 degree weather but comfortable none the less. The food was delicious but simple. Presentation was second to none. The host and hostess were extremely accommodating. Would love to stay there again.

I travel for my job, and was home in Casper for Christmas with my children. The day after I had an opportunity to meet a friend from Sheridan. I wanted someplace special, and found it. Our stay was an unforgettable experience. The home is incredible, and the staff was awesome. Everyone went above and beyond to accomodate. I had a connection problem with the wifi, and the manager didn't stop until we resolved it. It snowed overnight (how cool is that!) and in the morning, the lot was plowed and our cars were swept clean. Thank you for your hospitality. I highly reccomend this establishment. I love Victorian architechture, and this had it all. 12 out of 5 stars! Jim

Forty miles South of Buffalo is a place called Hole-in-the-Wall. A couple of fellows named Parker and Longabaugh You probably know them as Butch Cassidy and the Sundance Kid. The Hole In The Wall has a queen size bed, desk, chairs to lounge, a large bathtub, and separate shower. The original free standing claw foot bathtub is a hit with travel weary guests. The tub room is ensconsed with Wainscote and plaster walls. When you get in the bathtub, your cares go away, doesn't make any difference if you are a cattle rustler or the sheriff.

Rendezvous Room

The Rendezvous Room is at the back of the building. So named as history tells us, not everyone came in the front dooor. It is quiet, small, and welcomes the morning sun. It has a comfortable setting and warm atmosphere. It has a queen size bed with a country quilt. An antique pine desk is there for writing letters or dropping your keys down from a long drive. The wood floor has been gathering patina for 110 years. The bathroom has a shower and the original sink. Oversize colorful towels accent this room. Business meeting or other, the Rendezvous is a great room.

Cattle Baron's Room

The invasion of Johnson County in 1892 by the local cattle barons of Wyoming is history itself. We leave it up the other wonderful history scholors at the Jim Gatchell Museum here in Buffalo to give you the details and facts. What we think is the Cattle Barons planned the invasion of Johnson County from a room somewhere in Nebraska, similar to this one. The Cattle Baron Room is in the back corner. The bed is a regular size and the bathroom has a tub/shower. It is accented with colorful oversized towels. It is a wonderful place to spend a relaxing day or weekend.
