Mercedes's Airbnb was very clean and right next to a train and bus stop for easy access into downtown San Sebastian. The kitchenwas filled with the basics you needed and the beds were comfy. The only downsides to the stay was the building was under construction and it smelt like sewage. The workers worked from approximately 0830 to 1800 each day, so we basically forced ourselves to be gone all day so we didn't have to hear the noise. I'm not sure what they were working on, but it constantly smelt like sewage outside the building and most of the time you could smell it in the apartment. There was one fan in the apartment and air freshener spray which helped some but definitely not my ideal of a stay.
Overall, I'd definitely stay again after the construction was complete!
