We loved staying at Andoni's place. It was larger than we expected based on the photos. Really stylish inside, the courtyard was great and the windows opened right up to let the cool air in. The beds were super comfy - our 5 year enjoyed the sofa bed as well. I am not sure that there could be a nicer apartment with such a great location in all of San Sebastian.
The cupboards had all the basics which is a huge help when travelling as a family. We are Superhosts ourselves and are pleased to learn a few things from Andoni.
Totally recommended.
