Juan's apartment is truly amazing!! Location is fantastic - especially for the conference centre which is a 30 second walk away. The place is extremely well equipped, clean, sleek and comfortable. It also seems to be a permanent vacation rental (rather than someone's home) which means that it is like a fancy hotel! There were complimentary toiletries, chocolates, maps etc... I never met Juan but he sent his lovely colleague to meet with me when I arrived and the whole process was super easy. I would recommend the place to everyone and would definitely stay there again if I was back in San Sebastian.
