We had a great time staying at Gonzalo's place. The apartment is both on a hill and on the 7th floor of the building so has breathtaking views over the sea & Lekeito island. We spent every evening enjoying a glass of wine on the balcony and watching a dramatic thunderstorm one night! The apartment is spacious, airy and comfortable - with shutters and double glazing which kept everything cool and quiet. We visited San Sebastian one day but the rest of the time just hung out at the beach which is perfect for swimming - sheltered and calm. We also enjoyed walking over the causeway to the island at low tide and climbing up to the top and looking out over the ocean. I would really recommend Gonzalo's apartment.
