This is a free shelter inside the Parish “La Parroquia de Santa María y San Pedro”, but somewhat deficient (especially the showers!), that is the reason why some pilgrims in Belorado prefer to go to a private one and pay 8 euros. But I liked it.
There is a table with fruits and coffee with milk and biscuits for the pilgrims passing by, all is free, but you can leave a donation in a box.
They also have a library with plenty of books about the Camino that you can consult.
