As I walk in late autumn/winter, the albergues I stay in are almost always empty, so my experience may be very different from somebody who finds every bed full, especially in the smaller albergues. These albergues, in no particular order, stick in my memory (for good reasons):
Albergues municipal/turistico: Aldeanueva del Camino, Grimaldo, Fuente de Cantos, Guillena, Mombuey, Tábara, Morille. Next time I'm in Carcaboso l'll probably stay in the albergue turistico, rather than Señora Elena's private albergue (which was fine, but the turistico looked even nicer). Manuela's at La Calzada de Béjar was another nice private one, but there's nowhere to eat in the village, so remember to carry food (l didn't) - oh, and also remember (l didn't) to use the cash point in Baños de Montemayor, it's the last one before Salamanca.
All the Galician xunta albergues I've stayed in were good (Vila de Barrio, Ourense, Cea, Lalín, Ponteulla), although the blasted movement-sensitive lighting system at Lalín means you have to jump up and down every 2 minutes if you want to read a book.
Religious albergues: Fuenterroble, Alcuéscar, Oseira. If you stay in Alcuéscar, do try to get to the serene visigothic church of Santa Lucía del Trampal (a bit under an hour's walk out of town), and at Oseira vespers with the last surviving trappist monks is unforgettable.
Wherever you stay, you'll have a wonderful time seeing amazing places and going through fabulous countryside meeting delightful people. Buen camino, wish it was me going in September but my sheep keep me busy then.
