In winter it is a good idea to either check if albergues and other accommodation is really open even if they are supposed to. There is a list being updated almost every day, by a woman from Fromista, from November to February. The list is only for Camino Francés. Either check that list or call the place to see if the place is open. The list does not contain all open albergues, but a lot. I added a link to the list from the dashboard of the App.
