We stayed at the house for a week with a group of 9 friends. The house itself was great! We were kindly welcomed by Jean Pierre who gave us some great tips on what to do in the area.
The ruins of Donzy are nice to visit, and the hilly region is beautiful to walk through. Otherwise there is little to do for tourists in Panissières itself, it's just a regular French village.
Luckily there are large cities (Lyon and Saint-Etienne) within a one hour drive. The same goes for the Beaujolais wine region, which we visited multiple times.
All in all, we really enjoyed our stay!
