There are pros and cons to everything. For example, cities such as Valencia, Barcelona, Madrid, Malaga and Alicante are large and popular centers with developed infrastructure and busy lives, but the rental price naturally bites there.
For example, according to the
Idealista website for February 2025, the average price for renting an apartment
in Valencia is 15.2 euros per square meter, and in the satellite city of Torrent, which is located ~15 km (and 20 minutes by metro) from the center of Valencia, the price of housing is already 10.5 euros per square meter, that is, by
31% cheaper. And in the Barca suburb of Viladecans (~16 minutes by train), rent is
37% cheaper than in the Catalan capital.
Note that the actual rental prices are very different from the Idealista statistics. In the same Valencia, you will not find an apartment of
60 m2 for 900 euros (it will cost about a 1000 euros/month or more), but the percentage remains. Suburbs and small towns are much cheaper.
If you consider that transport in Spain is very developed (urban bicycle networks, subways, buses, trams, trains), movement can be organized without unnecessary transfers and wasting time.
