Just stayed there 2 nights at a place we found on Airbnb, at the eastern end of Zurriola beach. Lovely family / good location but parking out in the street a bit restricted and shared loo opening onto the living room / kitchen not to her nibs taste!
If you go the Airbnb route, watch out for the service charges, they take around 10% on top off you plus any cleaning charge which the owner shows on their page.
