San Sebastián
One of the most tightly held city markets in Spain: a small centre between two hills and a bay, with belle-époque buildings, three beaches and a food culture that draws people all year. Supply in the Área Romántica is finite and almost never new.
Life here
- La Concha and Zurriola
- Walkable historic centre
- World-class food
- French border nearby
Ownership rationale
Demand is domestic, Basque and increasingly French, and it is steady rather than seasonal. Value concentrates in the Área Romántica and Gros, where nothing new can be built and the best apartments trade quietly.
Getting here
San Sebastián airport at Hondarribia is 20 minutes; Biarritz 45 minutes and Bilbao around an hour.
The market, honestly
Published data where it exists — sources belowPrice per square metre
€8,905 / m² in the Centro; €6,600 – €7,100 / m² city-wide
Fotocasa puts the Centro district of Donostia at €8,905/m² (May 2026), with an average apartment value of €930,455, against €7,121/m² for the city as a whole. idealista has the city at €6,611/m² — Spain's most expensive capital by some distance. Buildings to renovate in the Centro trade below these figures, which is where the margin is.
Last three years
+10.4% year on year
idealista: Donostia rose 10.4% in the year to February 2026 and has held the title of Spain's most expensive capital throughout. Supply is structurally capped — the city is boxed in by hills and sea, and the Centro is fully built.
Rental return
3 – 4% gross on long lets (our estimate)
Not a published figure. Tourist licences in Donostia are tightly restricted and effectively closed in the Centro; underwrite on long lets, not nightly rates.
Holding and resale
€3,000 – €6,000 a year (our estimate)
Typical annual running costs including taxes, utilities and basic maintenance. Excellent. Central Donostia is one of Spain's tightest and most defensive markets.
Who this suits
- Buyers who want capital preservation ahead of yield
- Owners willing to renovate to buy into the Centro below the finished price
