Before arrival I was sent lots of information including google maps of how to get to the apartment. Very friendly and patient with us arriving later than expected also.
I stayed with my two daughters for 10 days for a dance competition nearby.
Apartment was a good size, comfy beds, clean and a very short walk to the beach. Lots of shops, bars, restaurants very close by. Would highly recommend and if we were ever to visit San Sebastian again, I would definately return.
