One reason why people travel to San Sebastian is to visit the great restaurants and pintxos bars. If this is why you are going, you should stay here. Only 50m from the old town where there is more food than you will ever have time or space to eat!
David's place is on the top floor of a beautiful 19th century apartment block with easy access via a spacious lift. The pictures don't quite tell you how spectacular this place is. It is HUGE by European AirBNB standards, and from the balcony you can see the Kurhaal and the old town.
The apartment is very well appointed. Everything you need was provided - including umbrellas, detergent for the washer, milk, some food, and we even found emergency sanitary napkins. David left us a list of recommendations for pintxos bars. We checked them out and we can totally recommend them.
Some very minor downsides. The toilet is located inside the shower cubicle which meant that you MUST use it before showering, and you have to remove the toilet paper before showering otherwise it gets wet.
Otherwise, I really enjoyed my stay here and would definitely stay again if I came back to San Sebastian.
