San Sebastián - Portuetxe bidea

Parking next to a bus stop that connects to the city center. Since the SS area is always full, we found this place while wandering around; it didn't appear as a parking spot on the apps, and we spent two nights. It's a seemingly safe place, next to a hotel, and since it's in a "polygon," there are many businesses with video surveillance. The downside: traffic noise. The polygon opens its doors after 6 am. It's not the best place in San Sebastián to spend the night, but it's free and has a bus stop.
