We stayed at Leaning Tree for our first-ever trip to Hocking Hills in January, and it was perfect and everything we wanted. It was extremely clean when we showed up. They use a lockbox for the key, so there was no checkin or checkout hassle. The hottub was hot and running when we showed up.
One thing for future visitors to keep in mind: the driveway is gravel and somewhat steep. We left our Toyota Corolla at the end for fear that we would have trouble getting out due to the snow and ice. This wouldn't be an issue for an AWD vehicle, and would only be an issue for small cars in the winter. The driveway wasn't long at all, so parking at the end was still convenient.
I would absolutely stay here again. Plus
