I had to respond to the poor review someone else posted.
I stayed that the Teton Treehouse a few summers ago and had the BEST experience.
The two owners are wonderful and treat you like family. They are incredibly knowledgeable about the area and offer great tips and ideas as to what to do and places to see. The breakfast was delicious.
The house is built up on a hill and it DOES feel like you are in a treehouse. The house is very cozy and comfortable with plenty to do such as read and play games.
If you are looking for a unique get-away and experience in Wyoming- you should stay here. I can not think of any negative to say about this place. It's absolutely WONDERFUL!!!

My family stayed with Sally and Denny for 3 nights in August 2006. We loved the relaxed Western family-style decor, the great breakfasts and the comfortable rooms. The conversations at breakfast were always interesting, and Sally made sure to include everyone, including my two sons, ages 15 and 13. The boys enjoyed the array of puzzles and brain teasers set out in the living room. There were also books, games and a piano. Our hosts were very knowledgeable about the different activities, trails and wildlife viewing opportunities in the area. We would love to stay here again on our next trip!

Jackson highlights for us:

My husband and 15 year old son rented bikes for 3 days from Wilson Backcountry Sports, just a few miles from the B&B. There are many great, relatively flat bike trails around Jackson, and the store had maps and lots of gear.

My 13 year old son and I enjoyed the National Museum of Wildlife Art and the Ripley's Believe It or Not Museum.

We all had fun at the rodeo, which drew a large family crowd, and we enjoyed the 4 PM Barker Ewing float trip, during which we saw bald eagles, a moose, mergansers and a beaver. We have great respect for the oarsman!

Don't miss the great pies at The Bunnery!

We spent four nights with Sally and Denny while exploring The Tetons and enjoyed it very much. They were great hosts and served amazingly healthy and tasty breakfasts. Denny even packed us some sweet breads for our early flight our last morning.

Our room was very comfortable, with large windows for viewing nature and falling stars :))) The inn was very beautiful and really did feel just like a tree house.

One caution, though. You really do have to climb 95 steps to enter the inn. They are quite manageable, but it is important to be prepared for the hike each time you return.

Yes, we would definitely stay at The Tree House again and hopefully will.

The description of this bed and breakfast stated it was a treehouse. It was not a true treehouse but a house built in several levels on a hill among the trees. The breakfast was fairly good but not a country breakfast like we're accustomed to. The biggest inconvenience was the policy they have (which is not posted on their website) is no showers after 10:00PM. The reason is because it makes too much noise. Quarters are small and close together. Don't bring children here. They wouldn't be free to run and play. I wouldn't stay here again.
