The house has truly gorgeous view. We enjoyed having breakfast everyday at the garden overlooking the beaches. The house is simple and not "fancy", but very clean and has everything necessary to stay comfortably... kids especially loved the toy horse, as well as climbing the ladder to the bed. The house is 10-15 min drive from the old town but the taxi is easily accessible (10-15 Euro for one way), and we can always go down to the beach in the morning/afternoon in 10 min. There are goats and chickens along the way to the beach which was also enjoyable for the kids.
Finally, Masa is very easily accessible and tries to help as much as she can. Overall highly recommended for anyone who wants to visit San Sebastian. We hope to come back again.
