San Sebastián (Donostia) property prices: the north's priciest market

San Sebastián / Donostia is the city with the highest property price per square metre in Spain after the most expensive areas of Madrid and Barcelona. With an overall average of €4,500-6,000/m² and areas such as the Centro, Antiguo or Gros nearing €7,000-9,000/m², the Donostia market is out of reach for the typical yield-focused investor looking for a 7-10% return. Rental yields in San Sebastián are in the 3.5-5.5% range, similar to those in the most expensive areas of Madrid or Barcelona.

So why devote an article to San Sebastián for investors? Because the Donostia market has features that make it attractive to a specific profile: the investor with more capital who is looking for long-term capital appreciation, a highly liquid asset and access to a market where demand is structurally strong and financially solid.

Real yields in San Sebastián

An 80m² flat in Intxaurrondo bought at €3,400/m² (€272,000) lets for €1,100-1,250/month. The gross yield is 4.9% to 5.5%. An equivalent flat in Gros at €5,500/m² (€440,000) lets for €1,400-1,600/month. The gross yield falls to 3.8-4.4%. These are yields that investors used to inland markets consider insufficient, but that premium-asset investors accept because capital appreciation makes up for them: San Sebastián prices have risen consistently faster than inflation over the last three decades, without exception, apart from the 2008-2012 period.

Why San Sebastián's prices are structurally so high

Three factors explain San Sebastián's structurally high prices:

• Physical constraints on supply: San Sebastián is hemmed in between the Cantabrian Sea, the River Urumea, Monte Igueldo and Monte Ulía. There is no land available for development. The whole city is built up, and any new property requires demolishing an existing one.
• Financially solid demand: The Basque Country has the highest GDP per capita and wages in Spain. Buyers and tenants in San Sebastián can afford to pay more than the Spanish average.
• The gastronomic and tourist effect: San Sebastián is the city with the most Michelin stars per inhabitant in the world. Its positioning as an ultra-luxury gastronomic and tourist destination—the Film Festival, the Jazz Festival, the Semana Grande—generates high-end short-term rental demand that pushes up residential prices.

The tourist rental market in San Sebastián: highly regulated

San Sebastián City Council has been one of the most active councils in restricting short-term tourist rentals. New VUT licences (vivienda de uso turístico, a licensed tourist let) in the city centre have been completely frozen since 2019. Existing licences have a very high market value and are sold along with the property as an intangible asset.
