Hi ! It's not links, but recent experience !
I started from Salamanca on 22th of August 2017 and finished in SdC on September, the 13th. For the first three stages, I slept on basic Albergue (old school) in Robliza de Cojos, San Munoz and Alba de Yeltes with excellent and nice welcome : go to the first bar to have an answer for the key of the albergue. In Ciudad Rodrigo in a residencial . In Aldea de Obispo in Albergue Municipal, ask for the key in a bar also. From Almeida to Lamego, I slept in Residencial and I paid from 17.5 € t0 25 €, sometimes with breakfast, sometimes not. In Mesao Frio, the Hotel was definitively closed and finaly, I slept to Bombeiros Voluntarios : I tried to find a room, but had no opportunities. In Amarante, I went to the youth Albergue. In Guimaraes, I had to take an Hotel, because the youth albergue was full. In Braga, it was in a private accomodation "Obra de Santa Zita". In Ponte de Lima, I made junction with the Camino Portugues and I found Albergue de Peregrinos (public albergue : 6 €). In Pontevedra, rather than going to Caldas de Reis, I walked on the "Variante Espiritual" going to Armenteira, Vilanova de Arousa and finaly, in Pontecesures, I met the Camino Portugues again.
I used a GPS and it was useful sometimes, especialy on first stages !!!.
