Renting in Madrid as a student: where to look and how to spot a fake listing
Studying in Madrid? Where to look for a room or flat, how your university can help, the details that give away a fake listing, and what to do if you've already paid.
You've got your place at university. Now you need a place to live, ideally close to the metro, affordable, and sorted before term starts. So you're scrolling through rooms at midnight, from another city or another country, while everyone else is doing exactly the same.
That's the situation a student at Universidad Carlos III de Madrid (UC3M) described recently on Reddit while looking for a flat near Fuencarral. It's a very normal situation. It's also the one rental scammers look for: lots of demand, little time, and people who can't easily turn up for a viewing.
Here's where to look, what a fake listing tends to look like, and what to do if you think you've already paid one.
Where to look
Start with Frankly
Frankly is a Madrid property site with a Rent search by neighbourhood, and it shows how each asking price compares with similar homes nearby. That makes it a good first stop for a feel of what a fair rent looks like in the area you're considering. You can also paste an Idealista or Fotocasa link into it to check that listing's price.
Your university
Alongside the portals, check what your university offers. UC3M, for example, runs a student accommodation information service covering halls of residence and colegios mayores (university halls, often with meals included) near its campuses, shared flats, host families and companies it has agreements with (UC3M). Its accommodation page lists those partner companies and the halls on the Getafe and Leganés campuses (UC3M Alojamiento), and UC3M's information centres also give accommodation advice (UC3M Youth Information).
Two things worth knowing from UC3M's own pages: university hall places are limited and demand is higher than supply, and the university also points students to noticeboards in its buildings where students offer rooms in shared flats. If you study elsewhere, ask your university's student services or international office what they have.
The portals
Most private rooms and flats are advertised on property portals such as Idealista and Fotocasa, and on room-sharing sites. Portals are a normal place to search, but a listing being on a well-known site doesn't prove it's real. When the consumer association OCU tested eight portals by posting a fake flat, none of them detected it (OCU, 16 Sep 2025).
Student groups
UC3M also points students to student associations such as ESN UC3M and their social media groups (UC3M). Groups are great for tips and flatmates. Treat any listing posted there with the same checks as anywhere else.
Red flags: when the details don't match the story
Most fake listings tell a believable story. The giveaway is usually a detail that doesn't fit.
You're asked to pay before a viewing
The first piece of advice from official sources, including INCIBE (Spain's national cybersecurity institute) and the Banco de España, is not to pay before you've seen the flat. We explain why in No viewing, no money. A reserva (holding deposit) isn't a scam in itself, but it should come after you've seen the place, with something in writing, paid to an account in the name of the landlord or agency.
Nobody can show you the flat
The owner is abroad, working away, or "the keys are with a lawyer". Lots of honest landlords live elsewhere. The warning sign is when nobody can show you the flat and you're asked to pay anyway. INCIBE lists owners who can't show the flat as a warning sign (INCIBE), and ECC-Net warns about keys handed over by post (ECC-Net).
If you can't travel yet, ask someone you trust to view it, or do a live video call you direct from inside the flat, as IE University suggests (IE University). A video call shows someone has access, not that they have the right to rent it, so still check who you're paying.
The rent is far below the area
Spain's Interior Ministry advises comparing an offer with market prices (Ministerio del Interior via La Moncloa), and the Catalan government's youth portal lists bargain prices as a sign of "ghost" flats (Jovecat). Look at similar rooms in the same barrio (neighbourhood). If one is much cheaper with no clear reason, ask why.
Other details that don't fit
- You're pushed to pay quickly because "lots of people are interested".
- The chat moves off the portal and towards a payment or payment link.
- You're asked for your passport or DNI (Spanish ID card) before any viewing. The Interior Ministry advises against sending your ID.
- You're asked to pay through anonymous money-transfer services (Agència de Ciberseguretat de Catalunya).
And two numbers worth knowing: for a long-term home rental, the fianza (security deposit) is one month's rent (LAU art. 36.1), and the landlord can't demand more than one month's rent in advance (LAU art. 17.2). The LAU is Spain's tenancy law, Ley 29/1994. If you're asked for much more, ask why, in writing.
Check the listing before you pay
Paste the listing into our free checker at justisimo.es/check. It looks for details that don't match the story. It can't prove a listing is safe, so keep the "no viewing, no money" rule either way.
If you've already paid
It happens to careful people too. Act quickly:
- Call your bank straight away. The Banco de España says your bank should make reasonable efforts to recover a transfer, but once the money has reached the other account it can only come back with the recipient's consent or a court order (Banco de España). Speed helps.
- Save the evidence: the listing (screenshots, with the URL), every message, the bank receipt, the account number and any names or phone numbers. Don't delete the chat.
- Report it to the police. You can make a denuncia (police report) at any comisaría (police station), or start one online at the Policía Nacional's Oficina Virtual de Denuncias. An online report has to be signed in person at the comisaría you choose within 72 hours, or it has no legal validity. The online form doesn't cover every case, for example when you know who the author is.
- Report the listing to the portal so it can be taken down.
- Get help: INCIBE's 017 helpline is free and confidential, open 8:00 to 23:00 every day, and also on WhatsApp at 900 116 117 (INCIBE 017).
Being scammed says nothing about you. It says the scammer was good at telling a story.

FAQs
Does UC3M have an accommodation service? Yes. UC3M offers accommodation information covering halls, colegios mayores, shared flats, host families and partner companies, plus advice at its information centres. Hall places are limited, so look early.
Is a listing on a big portal automatically real? No. OCU managed to post a fake flat on eight portals without being detected. Use the same checks everywhere.
The landlord lives abroad. Is it a scam? Not necessarily. The warning sign is when nobody can show you the flat and you're still asked to pay.
How much can a landlord ask for up front? For a long-term home rental: a fianza of one month's rent (LAU art. 36.1), no more than one month's rent in advance (LAU art. 17.2), and possibly an extra guarantee, which is capped (LAU art. 36.5).
I paid by Bizum or transfer. Can I get it back? Maybe, but not automatically. Call your bank immediately and report it to the police.
Do I have to go to a police station? To make the report valid, yes: either file it there, or start it online and sign it at the comisaría within 72 hours.
