You are highly unlikely to find a better apartment in San Sebastian for a large group. Spectacular view, easy access to shopping and restaurants, well-supplied kitchen, beautiful and clean throughout. Do not even hesitate to reserve this place.
Natalia and her assistant Valeria were superb hosts and most helpful throughout our stay.
One hint: The wifi router is in a closet, so keep the closet door open for better wifi reception. We absolutely loved this place!
