I would add to your list this sweet refugio in Lorca, called JoseRamon albergue de Lorca. Small and friendly guy...we are eating all together with a few of us cooking. 7€, a bocadillo with a beer o vino 3€. Washer, free Internet, small rooms accomodating either 1 bed, 2 beds or 4 persons in bunks. Clean as anything I´ve seen.
