I recently stayed at the Timberlost Cabin, and I must say, it was a surprisingly disappointing experience.
To begin with, the pictures online were incredibly deceiving. The cabin looked charming and rustic in the photos, but in reality, it is a Warehouse which converted to a Cabin. The entrance is not providing a good vibe and steps leading to the main cabin is not proper.
Upon entering, I was hit with a musty smell that suggested the place hadn't been properly aired out in ages. The furniture was old and uncomfortable. The kitchen was another letdown. There is no dishwasher.
Same scenario with the bathroom and was perhaps the worst part of the cabin. There is no privacy with the one of the room. If the cabin can accommodate 4 people at at a time, I would definitely have to say that the bathroom will give you hard time.
Additionally, the view from the cabin was obstructed by overgrown bushes and trees. There was no proper path to explore the surrounding area and mosquito all around the place.
Overall if you are going to UP for relaxing in a group, this is not the place definitely.
