Gustavo's penthouse is perfectly located in the heart of the old town in San Sebastian. While small, it is perfect for two people and has been very cleverly designed to make the most of the limited space available and create a sun terrace which is well integrated with the interior. Gustavo generously provided a large bowl of fruit and other essentials in the fridge. We had not been to San Sebastian before and this made an excellent base from which to explore what the town has to offer
