Thank you for a great stay! The apartment was modern, cool and clean, and the location is great, with walking distance to the old town! On the constructive side, the apartment lacked some basic utilities that one should expect from such an apartment, like more kitchen utilities (especially since the kitchen is otherwise great). A delayed check-in is also understandable, but unfortunate.
All in all a great experience that I would recommend for a group spending a few days in beautiful San Sebastian.

Andreas
