After fleeing the Garabit Hotel, located 500 meters away, I was greeted by the owner, who was absolutely lovely. Everything was perfect: the room was spotless, and the restaurant was excellent. I highly recommend staying here if you're passing through the area, rather than at the hotel mentioned above.
A hotel in a great location for visiting the viaduct.
Furthermore, the receptionist was very pleasant and helpful.
The evening meal was very good.
If I had to mention a negative point, it would be the size of the toilets :)
A very warm welcome, excellent restaurant, and an absolutely perfect room (bathroom, bedding, view of the Garabit Viaduct). We highly recommend this establishment.
