Beñat was a fantastic host.
Upon arrival he met us at the train station and drove us to the appartment, highlighting places of interest on the way. He had a lot of information prepared at the appartment on what to do and see in San Sebastián along with a list of the best pintxo bars. We visited a lot of his recommendations for pintxos and they were all great.
The appartment is lovely, it's very clean, has a washing machine and is situated around 15-20 minutes from the beach.
I would highly recommend this place to stay and Beñat as a host.
