I looked at the attachment on jenny@zen's post and that was in April which attracts more tourists to the river valley for rafting and fishing. There are several hotels/hostel, as mentioned, and some places that offer camp grounds and cabins but November may be well past the season they are open. Besides, Covid has killed the dining and lodging industry there. It may be painstaking and end up being a worthless effort but I would go to Google Maps and look at the layer for hotels/lodging and/or dining facilities (some restaurant may have rooms to rent) along the road between Bayonne and SJPdP and see what you come up with. My next best suggestion would be to contact Monasp at the pilgrim office in SJPdP by PM on the Forum.
