From the moment we saw the photos and contacted Gustavo, everything went smoothly. He always responded promptly and even offered suggestions from transportation from Bilbao. Gustavo met us at the apartment and explained everything. The apartment was perfect! It was very clean and well-furnished and well-maintained. The terrace was so lovely for evening drinks. Location couldn't have been better. A supermarket with wonderful options for cured meats, cheese and antipasti is on the next block. The Parte Vieja begins 2 blocks away. The beautiful river walk is at the end of the block and the beach is a 5-minute walk away. I would definitely book this place again next time I come to San Sebastián.
