We definitely recommend this apartment! The apartment is clean, the room has enough space and the temperature is good. If you close the window, the noice of bar underneath the apartment does not really bother.
Close to the beach (Zurriola) and a 15-20 minute walk to the old centre. We spend most of our time in the old centre (eating Pinxos and drinking cider ;)) but it was a nice walk next to the beach to the apartment.
Last, Pedro allowed us to store our luggage his apartment for a few extra hours (our bus left at 16h), which was very nice!
