I booked the Tranquility cabin. Overall, I would rate this cabin a 4.5 (but I highly recommend reading over the contract on their website—they charge a cleaning fee and non-refundable damage deposit).
The cabin was easy to locate, secluded, and perfect for us. We checked in by phone and the woman who answered was very pleasant. The cabin looked exactly as I always expected and is located up in the mountains 30 minutes from Pigeon Forge, which was exactly what we wanted. They had a bear theme, which was cute and sophisticated. Furniture was in great shape and comfortable (including the beds). However, the wood frame for the doorway to the washer and dryer had been removed.
Cleanliness was just OK. It wasn't dirty per se, but it hadn't been dusted in a LONG time. It set off my allergies and I had to use my inhaler. There were piles of dead bugs in the corners. Lightbulbs needed to be replaced. A wet washcloth was decoratively tucked into a towel. And we found dirty boxers under the bed.
All in all, it was a charming cabin that lived up to its name. I'm already planning another longer stay near the holidays.
