Nathalie is an absolutely wonderful host, and her dogs are amazing, although I didn't get to see them much through my stay.
Once I found the cabin (with Nathalie's help), I was left to my own devices to enjoy the beauty of the area, and it was genuinely stunning. The landscape is incredible and there are hidden places to explore, with streams, lakes, and off-paths to be found. A lot of places around the cabin are private land, but there is still plenty to explore.
The cabin has almost everything you need, but make sure you bring something to light a fire, and get some firewood. I didn't bring either, so I walked about 2.5h to the nearest village, Huberdeau, and I very much recommend this gorgeous walk to anyone in the area; everything on the way is beautiful.
In the town, they were only selling firewood in bulk, which I didn't need, so I only bought a lighter, and collected firewood on my own, it's plentiful throughout the area, but a bit hard to light when things are damp. It gets cold at night, be prepared to sleep fully clothed, even with a fire.
Overall, the experience was otherworldly for someone like myself who has never experienced such wilderness. Would absolutely recommend to everyone!
