We enjoyed our stay in the mountains of TN. The description online is spot on, it's a beautiful and unique opportunity found settled among the trees and nature.
I would describe it as a top-shelf efficiency tiny home. Everything you need is there, it's cozy and beautifully maintained. You are settled next to Ms Carol, the gracious owner who insists on your privacy. I would however recommend, chatting with Ms Carol, she's delightful :)
A wonderful stay, and we hope to return someday.
