On my very first Camino, I was walking with a friend with a serious mold allergy. She was fine everywhere, except for O Cebreiro and San Juan de Ortega. O Cebreiro, I've seen, has been totally remodeled, so hopefully the problem is gone. San Juan de Ortega has probably gotten worse. Beautiful spot, gorgeous church next door, but the albergue would not pass a health inspection. Buen camino, Laurie
