According to a recent report from the real estate portal Idealista, the rental market in Spain’s major cities, particularly for single rooms in shared apartments, has seen widespread price increases over the past year. Rental costs in the capital, Madrid, have once again become a major focus of market attention.
Madrid Rents Continue to Rise, Among the Highest in the Country

The report’s data shows that the average monthly rent for a single room in a shared apartment in Madrid has now reached €550, a 4% increase compared to the same period last year. This price point makes Madrid the second most expensive city for renting in Spain, surpassed only by Barcelona, where the average monthly rent is a steep €600.
Among other major cities, Palma, the capital of the Balearic Islands, also has an average room rent of €550. In the northern city of San Sebastián, the average rent is €500, while in Bilbao and Málaga, it stands at €450.
Rental Supply Grows, but Demand Shows Divergence
On the supply side, the number of available rooms for rent in Madrid increased by 17% year-over-year in the second quarter (April to June), a growth rate higher than the national average of 12%. Madrid now accounts for 23% of the total rental room supply in the country, leading all Spanish cities. It is followed by Valencia (15%), Barcelona (11%), and Seville (3%).
However, a noteworthy phenomenon is that despite the increase in available rooms, the number of potential renters per available room in Madrid has actually decreased by 9% over the past year. This is in stark contrast to the national trend, where the number of potential renters increased by 12% during the same period, indicating a subtle shift in the supply and demand dynamics of the Madrid market.
Overview of Spain’s National Rental Market
Across Spain, rents in the shared housing market have generally continued to rise. In the second quarter of this year, the national average monthly rent for a single room in an apartment was €425, a slight 1% increase from the same period last year.
In terms of rent hikes, the growth in some cities has been particularly significant. Palma saw a staggering 22% increase, followed by Teruel (17%), Palencia (16%), and Castellón (11%). These figures suggest that the pressure of rising rents is spreading from traditional major cities to more second and third-tier cities.
