Gustavo is the perfect host. His apartment is amazing & in the best possible location; in the middle of everything yet the apartment is silent. We were met by Gustavo at the arranged time. He sorted parking for us & showed us around the apartment. He gave us great tips on places to go see. He was on hand for any questions. I couldn't speak more highly of him as a host or of his apartment. We will certainly be back in San Sebastián some day & there is no doubt we'd want to stay with Gustavo again. If you're going to go to San Sebastián...take my advice...stay with Gustavo!
