The 4 Best Apps to Find a Flat in Spain in 2026

The instant alert is your weapon: set it up on idealista and Fotocasa with your exact criteria and reply within minutes, not hours, with a short, complete message (who you are, your income, when you can visit). Have your paperwork (payslips, employment contract, references) ready as PDFs on your phone so you can send it straight away: in tight markets, the first person with their papers in order usually gets the viewing... and the flat.

For a whole flat, idealista + Fotocasa (use both: the listings don't fully overlap) and keep an eye on Milanuncios for private owners. For a room in a shared flat, Badi is built exactly for that: you can see what your future flatmates are like (age, habits, schedules) before writing, something the generalist portals don't tell you. In expensive cities, sharing via Badi is often the only realistic way to move out.

The classic signs: a price well below market, an owner 'abroad' who asks for money before showing the flat, and artificial urgency. Golden rules: never pay anything (deposit, bond, 'reservation') without having visited the flat and checked that whoever is renting it is the owner or their representative, be wary of communication outside the platform, and use the app's chat, which leaves a trail. The portals do take down fraudulent listings, but they are always playing catch-up.
