We had a great stay in Myriam's place. Clean, comfortable bed and sofa bed, well equipped kitchen. A little noisy at night because of its central location should be expected. The location is just great for exploring the old town at night.
Myriam is a fantastic host. She will do what it takes to make you happy staying in the apartment. She speaks english without problem and answers on communicstion very fast.
Our warmest recommendation for letting Myriam host your stay in San Sebastian.
