Damaso’s apartment is great! In a good location a few blocks from the beach and close to many pintxos bars with better (&cheaper) pintxos than in the more touristy areas of the city.
The apartment itself is better than the pictures. It was comfortable, quiet and spotlessly clean!
Damaso was very accommodating, allowing us to leave our bags before the apartment was ready etc. And he gave us some good restaurant tips and a great overview of things to see in the city.
