A beautifully preserved 19th-century royal palace set in private gardens on the hillside above the city, converted into a five-star hotel with grand salons, individually furnished heritage rooms, and a spa. San Sebastián's most secluded and romantic address.

Perched on Monte Igueldo above the city with panoramic views of the Cantabrian coast, this design hotel is home to Pedro Subijana's three-Michelin-star restaurant and offers 22 rooms designed by Inigo Rotaeche with floor-to-ceiling ocean views. The most extraordinary restaurant-hotel experience in the Basque Country.

The grand Belle Époque dowager of San Sebastián, opened in 1912 by the Urumea river with a theatrical neoclassical façade, lavishly restored rooms, and a history of hosting the world's most glamorous film festival guests. Widely considered the most iconic hotel in Basque Country.

A historic seafront hotel occupying a privileged corner of La Concha promenade with wraparound bay views from its upper-floor rooms and a terrace that may be San Sebastián's finest spot for an afternoon vermouth. Unpretentious, characterful, and remarkably well-priced.

San Sebastián's classic seafront address since 1904, with a magnificent white façade directly on La Concha promenade and rooms with bay and beach views at various price points. Queen María Cristina was among its earliest regulars — the unbroken tradition of aristocratic hospitality continues.

An outstanding small guesthouse in the heart of the old town, offering immaculate rooms above the very bars that make San Sebastián famous. Run by a family with deep local knowledge, it is the best budget accommodation in the city and books out months in advance.
