My boyfriend and I stayed in Columba´s flat 5 nights in July, and it was really a highlight of our trip to northern Spain; San Sebastián is amazing, and so is Columba. The apartment is located a bit away from the old part of town, but close enough to enjoy the walk along the beautiful beach promenade (20 min or so). Or you can take the bus/taxi if you can´t be bothered. Great views from the balcony, clean and nice apartment with all amenities, nice breakfast provided by Columba, and the best company. Will definitely stay with her again if I go back!
