AMAZING LOCATION. Leire's place is in the heart of Old Town, close to all the best pintxos spots and also very close to the beach. Noise was definitely an issue, but we expected that going in and Leire thoughtfully left us earplugs which we used. Also, we were there during a holiday week so the noise was a bit more than usual - still, we loved staying at this airbnb. It should be highlighted a bit more that you are likely to be sharing the apartment with other travelers. There are 3 bedrooms and during our stay, several different travelers were using the other 2 bedrooms. We saw them only a few times so it was never awkward for us. Leire was in and out of the apartment during our stay, but always quick with online communication if we did not have a chance to speak with her in person.
Overall, if you don't mind sharing the common spaces and can sleep through noise on the street outside the window, you should absolutely book this place - the location is really amazing and great value.
