The apartment is very clean, excellent position for going to the Zurriola beach (actually to everywhere, I walked till I dropped :)). 15 min walk to the bus station of San Sebastian (I arrived, and travelled from San Sebastian to Pamplona and Bilbao from the bus station), 15 min walk to the old town, pintxos bars.
Elur is very kind and welcoming, thoughtful, accomodating tourists to her ordinary life, growing a kid, etc
One detail is that the exterior of the building is under renovation, and there is no much natural light, but in the end, when travelling, you don't get to see the daylight in your room, isn't it?
