We had super time at Marco's apartment...the accommodation was spotless, very spacious and excellently equipped. Pepe was actually standing by the front door when we drove up and couldn't have been more helpful in getting us settled in. Marco responded quickly to any query and kindly let us stay a couple of hours past checking out time as noone else booked in. Very handy for the beach. It's about a 40 minute stroll into the old town ..good way to walk off the excesses of the fab pintxos bars. But buses every few minutes to near the apartment if it's too much at the end of the night. San Sebastian a great base and only an hour from Bilbao which is def worth a trip.
Would not hesitate in recommending...definitely the best Airbnb place we've stayed in. Only downside was it rained a couple of days..but even Marco couldn't fix that!
