The Malaga amigos are really great people. Very helpful. As you’ll have seen they meet in a room above a community centre about 1km out of the centre. I left with more souvenirs, books and photos than I could carry and needed an early visit to correos to send the loot home before setting off.
If you have time I’m certain you could make contact and sort something out. If not you can of course use the generic credencial. Widely available.
