The 4 Best Apps to Find a Flat in Spain in 2026
Flat hunting in Spain is a speed sport: the good ones are gone in hours and whoever has their alerts set up properly wins. Each portal also has exclusive listings, so searching just one means missing options. In this guide we compare the 4 best apartment hunting apps in 2026, including the room-share specialist.

idealista is the benchmark portal: the largest pool of listings and the instant alerts that make the difference in hot markets.
idealista is the leading property portal in Spain: the largest pool of homes for sale and rent, with instant alerts that make all the difference in hot markets (a good flat is gone within hours), a map tool to draw your own search area, and price data by neighbourhood so you know if you are overpaying.
Pros
- The leading property portal in Spain
- Instant alerts for new listings
- Draw your exact search area on the map
Cons
- In hot markets everything goes fast

- Agencies sometimes never reply
Fotocasa
Adevinta · Free · 10M+
The essential companion

212K reviews
TopApps analysis
Fotocasa has exclusive listings that aren't on idealista: searching both doubles your real options.
Fotocasa is Spain's second big property portal and the natural companion to idealista: part of its stock is exclusive, so searching only one of them means missing flats. With its own price index, alerts and fine-grained filters (terrace, lift, pets), running both searches multiplies your options.
Pros
- A large pool of flats that complements idealista
- Exclusive listings you won't find on other portals
- Its own price index
Cons
- Second in volume behind idealista
- Duplicate listings across portals
- Ads for new developments
Badi: Habitaciones
Free (with purchases) · 1M+
Best for shared flats
4.4
29K reviews
TopApps analysis
Badi is the room specialist: flatmate profiles with lifestyle details and direct chat, key in Madrid and Barcelona.
Badi is the Spanish app built specifically for renting rooms and house shares: flatmate profiles with interests and lifestyle, direct chat with no middleman, and user verification. In expensive cities like Madrid or Barcelona, where sharing is the norm, it is the specialist tool idealista is not.
Pros
- Built specifically for rooms and house shares
- Flatmate profiles with lifestyle details
- Direct chat with no middleman
Cons
- Less useful outside the big cities
- Visibility features cost money
- Fewer whole flats on offer
Milanuncios: Segunda mano
Free · 10M+
Straight from the owner
4.6
304K reviews
TopApps analysis
Milanuncios keeps something increasingly rare: listings from private sellers with no agency, dealing (and pricing) direct with the owner.
Milanuncios is one of Spain's longest-running classified ads platforms. You can buy and sell just about anything: cars, motorbikes, property, jobs, second-hand goods and much more. Its sheer volume of listings makes it the reference point for private sales and for dealing with professionals too.
Pros
- Huge volume of listings of every kind
- Covers cars, property, jobs and more
- Posting ads is free
Cons
- Less modern interface than Wallapop or Vinted
- Worth being wary of suspicious listings
- Plenty of trade listings mixed in
Frequently asked questions
How do I get a flat before it's gone?
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.
Whole flat or a room? Where do I look for each?
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.
How do I avoid scams when flat hunting?
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.
