We very much enjoyed our stay at Edurne's apartment. It was exactly as advertised and we appreciated that Edurne met us and provided us with drinks and snacks as a welcome.
The apartment was clean and had ample towels, bedding and kitchen supplies for the 2 of us. The laundry machine was appreciated as we stayed 8 nights.
As noted the apartment is in old town and the afternoon and evenings bustle with activities so it can be louder at times. Most nights the noise was perfectly fine with Saturday night being the only exception but with earplugs it was fine and we didn't find it difficult to sleep.
I would definitely recommend and would stay here again. Its just a block to the ocean and has fantastic bars all throughout Old Town.
