I'll summarize up top and go into further detail below.
Tl;dr - Immaculately clean, Pool, theater and games were fantastic - kids didn't want to leave the cabin. Hot tub was great. House is gorgeous and location is excellent. We've stayed in the smokies at least half a dozen times, and this is the best cabin we've stayed in, by a long shot.
Cleanliness - I've stayed in a dozen or more short term rentals, this was the cleanest.
Amenities - the owners have excellent taste. Decorations weren't over the top. They left out a hot chocolate bar which by 4 years old loved. Plenty of linens and soap. A bidet!!!!!
The pool was incredible. My daughter didn't want to leave. Between the theater and pool, we binged Toy Story 1 through 4 in one day. The games in the game room were awesome. Literally hundreds to choose from, if not thousands.
The hot tub was perfect, and something my wife and I utilized each night.
The location - just 12-15 minutes away from "the strip" (Pigeon Forge)and easy to get to. Roads are much better than other places we've stayed here.
Communication was impeccable and response times from Erin and Ken were immediate. We had no issues, just a few questions throughout the stay.
We will certainly be coming back, and would strongly recommend this or any other properties they own.
