If you looking for the true ambassador to Donostia/San Sebastián, then you found your man, Beñat! He was not only very friendly and kind, he was sooo helpful. He provided my partner and I with maps and lots of things to do and check out. He gave restaurant recommendations, advice on ordering food, hikes to check out, which beach was the most ideal also, where not to go because there's not much to see or do.
He picked us up from train station and drove us to his clean apartment. It had all the basic necessities. There was construction around the building, but it did not bother us. Beñat asked the construction workers to avoid working around the apartment during our stay, which was thoughtful. But you cannot avoid loud hammering and drilling, however we took it as our alarm clock to wake up and seize the day. His place is on top of a hill, it wasn't much of an issue for us as we live in a hilly city. The walk down to the water is about 15-20 minutes, depends how fast you walk.
Thanks again, Beñat! We loved our stay, only wished we were able to stay longer. We will be back!!!
