My wife and I booked Cozy Cabin almost a year ago in order to be in the path of totality for the eclipse. Cozy Cabin was a wonderful place to stay, it is absolutely a cozy cabin! Clean and well appointed with everything you could ask for. It's a perfect place for two couples, or a couple with 2 children to spend a few days.
The lake is beautiful, there are enough other cabins on it you don't feel isolated but they're far enough away to give you peace and quiet.
Cozy cabin itself is well-stocked with games to play, everything you need in the kitchen, excellent modern appliances, good water pressure in the shower, and a fantastic porch and yard to just sit and watch the lake.
I would be aware the last mile of road to the cabin is dirt & gravel. Our little Jetta handled it without issue, but in heavy rains it could get a little sloppy.
Magdalena and John were great hosts who responded quickly to any communication.
I would absolutely stay at Cozy Cabin again if I was looking for a weekend of peace and quiet away from the city.
