We needed to stay an extra night in San Sebastián and booked Gustavo's apartment. It was the best! It's spacious, beautiful and in the perfect location near all the amazing restaurants, bars and beaches. Not to mention, it had the most amazing terrace with a beautiful view of the city. Gustavo was extremely helpful and communicated with us the entire time leading up to our stay, answering all our questions quickly. We were sad to leave after only 1x night, as it is truly one of our favorite places we've had the pleasure of staying!
