We stayed for three nights in late May. We were two couples and a three year old and the place was more than enough space for us. There was even room for one more couple, given that it had three bedrooms and two full bathrooms. It was conveniently located in the old town within minutes of the market and restaurants and only about 10 minutes walk to the beach. Our terrace even overlooked a playground, which my son loved. The place itself was very clean and the hosts were very receptive to any questions we had regarding parking and checking out. We enjoyed our time so much that we even considered changing the entire trip to just remain in San Sebastián!
