We had a perfect stay in San Sebastian. Aiser communicated quickly with us at all times and the check-in was smooth. The apartment itself was perfect for us (4 adults) - plenty of space, 2 bathrooms, everything you need in the kitchen and a washing machine with space to dry clothes. The location is ideal, right in the middle of the main shopping area, 5 mins walk from the beach and 10 mins walk to the old town. Despite this central location, the apartment is completely silent as it does not face onto the street - instead you have a bright and sunny view of the courtyard and up to Monte Urgull. We also had parking which was conveniently located 2 blocks away in an underground secure space and very reasonably priced, this was fantastic given the always full public parking areas in summer.
