This apartment is gorgeous and in the most wonderful central location. It is so quiet at night and the top floor balcony has a lovely view. A great place to stay for longer as the kitchen is well stocked (many cups, wine glasses/accessories, coffee maker, large refrigerator) and we were able to do our laundry while there.
There are many wonderful bars and restaurants in the area and it is a short walk to Old Town. I would highly recommend staying here when in San Sebastian.
