Very lovely stay in San Sebastián. We stayed during the week and it was very quiet. There is a twin room on the street side, the larger bed in the middle off the street and the bunk bed was furthest off the street and nobody had trouble with noise. Apartment was surprisingly quiet for being in the city. Excellent location. Comfy (firm) beds. Short walk to surf, around the corner from restaurants and across the street from grocery store. Just a short walk into old town and some amazing sights. The hosts were incredibly friendly and gave top notch restaurant recommendations. Very clean apartment with many amenities. Would stay here again.
