Hola, Skol,
I stayed in Albergue Santa Marina in beginning of August last year. The contact info I had was:
Santa Marina 14
981-852-897 (land)
653-626-864 (cell)
casaantelo@gmail.com
I phoned ahead on the day of arrival but don't remember on which number. Albergue itself is the last building on the main street and owners have a restaurant (second one as the first doesn't offer accoommodation), you can't miss it. One large bedroom (6 beds) and bathroom in the attic, one smaller bedroom with 2 bunks, bathroom and equiped kitchen on the ground floor, patio. Price was 10€.
Nice owners, a couple, she's Spanish I believe and he's expat (English?, don't really remember).
Very close are two restaurants and panaderia where you can also buy some other food.
I have some photos of the place and can attach them if you're interested.
Ultreia!
