Poised between the rolling green hills of the Basque Country and the sparkling waters of the Bay of Biscay, San Sebastián is quietly redefining luxury living in Spain. Once a well-kept secret among food lovers and surfers, the city has now caught the attention of the world’s most discerning investors—drawn by its blend of culinary excellence, cultural richness, and coastal elegance.
According to the latest Global Property Handbook by Barnes International Realty, real estate transactions in San Sebastián doubled in the first quarter of 2025, a remarkable figure that confirms its growing status as a global luxury destination. The Real Estate Observatory attributes this surge to sustained, selective demand—particularly from international buyers seeking a refined lifestyle in an authentic yet cosmopolitan setting.
Where elegance meets the ocean
Home to just under 190,000 residents, San Sebastián feels both intimate and sophisticated. The city unfolds along a crescent-shaped bay, framed by soft sands and elegant Belle Époque architecture. Here, gastronomy is an art form—its cluster of Michelin-starred restaurants and celebrated pintxos bars are world-renowned—while its thriving arts scene and the famous San Sebastián International Film Festival ensure a lively rhythm throughout the year.
Yet it’s not just the city’s charm that appeals to buyers. San Sebastián offers something rare in Europe today: a perfect balance between nature, culture, and exclusivity. Luxury homes perched above the coastline, properties with panoramic views of La Concha Bay, and elegant apartments in historic districts are all in increasing demand.
The city’s most coveted corners
The Gros, City Centre, and Miraconcha neighbourhoods top the list for those seeking both prestige and convenience. Gros, vibrant and modern, borders Zurriola Beach—popular with surfers and cosmopolitan locals alike. The city centre enchants with its boutiques and fine dining, while Miraconcha, overlooking the famous beach, remains the epitome of seaside sophistication.
According to the latest idealista price report for September 2025, rental prices in Gros now reach €19.7 per square metre, while purchasing a home averages €6,708 per square metre—clear proof of the area’s rising desirability.
Spain’s global appeal
San Sebastián’s rise reflects a broader trend across Spain, which continues to strengthen its reputation as one of the world’s most appealing destinations for high-end real estate. The Barnes City Index 2025 places Madrid at the top of its list, highlighting the capital’s exceptional quality of life, safety, first-class healthcare and education systems, and vibrant cosmopolitan energy.
“Madrid’s appeal as a high-end property hub continues to grow,” explains Alvise Da Mosto, Associate Director at Barnes Spain. “With a favourable investment climate and a steady rise in international buyers, the city is consolidating its position as a global benchmark for luxury living.”
Following Madrid, cities such as Dubai, Miami, Monaco, and Milan feature prominently on the international list, while within Spain, Barcelona, Marbella, and now San Sebastián stand out as elegant expressions of the country’s modern luxury lifestyle.
