Apartments & Roommates in Madrid
A room in a shared flat in Madrid costs about €575-700 a month: Idealista put the 2025 average at about €575, and OCU found an average asking price of €689 in August 2026. Prices drop a lot as you move south of the river, where rooms in Carabanchel or Latina can cost €200-300 less than near the universities. What surprises newcomers: there is no rent cap in Madrid, and some rooms are offered without a contract or without the right to register at the address (empadronarte), so ask before you commit.

How to find a roommate in Madrid
Most people search on Idealista and Fotocasa (both have a rooms section), on Badi, an app for shared flats, and in Facebook groups for rooms in Madrid. Students coming from abroad also use Spotahome and HousingAnywhere, which let you book without a viewing, for a fee.
Viewings move fast: the flatmates or the landlord show you the room, and good rooms near the universities are often gone the same week. Demand peaks from July to September and again in December and January, when Erasmus and other students arrive for each semester. If you can, book a short stay for your first week or two and view rooms in person. You can also post a room or a roommate profile on Roomly.
- Can I register on the padrón at this address?
- Will I sign a contract, with whom, and for how long?
- Are bills (gastos: electricity, water, gas, internet) included? If not, how are they split, and what were the last winter and summer bills?
- How much is the deposit, and is anything else paid up front?
- Is the room exterior (window onto the street) or interior (onto an inner patio)?
What renting a room in Madrid costs
Idealista put the average room in Madrid at about €575 a month in 2025, 2% up on the year before and second only to Barcelona in Spain. The consumer group OCU looked at Idealista asking prices on 31 August 2026 and found a higher average, €689.
The barrio matters. In OCU's study rooms averaged about €759 in Universidad (Malasaña), €757 in Ríos Rosas and €751 in Argüelles, against €459 in Águilas, €483 in Abrantes, €509 in Vista Alegre and €512 in Palomeras Bajas (Vallecas).
- Bills (gastos): many ads say 'gastos incluidos'. When they are not, ask for recent bills: Madrid summers are hot and winters cold, so air conditioning and heating change them a lot.
- Deposit (fianza): one month's rent for a housing contract under the LAU, plus at most two months of extra guarantee. In the Comunidad de Madrid the landlord must lodge the fianza with the Agencia de Vivienda Social.
- Agency fees: under the LAU (article 20), estate agency and contract fees cannot be charged to the tenant.
- Booking platforms such as Spotahome and HousingAnywhere charge their own fee, often a large share of the first month's rent and usually non-refundable. Check it before you pay.
Rules and paperwork in Madrid
This is general information, not legal advice. Rental rules in Spain changed several times in 2025 and 2026, so check the official sources below, or ask a tenants' union or a lawyer, before you sign.
- NIE (número de identidad de extranjero): the identity number for foreigners. You need it for most contracts, bank accounts and jobs.
- Padrón: everyone who lives in Spain must register in the town where they live. In Madrid you do it with the Ayuntamiento, online or with an appointment, with your ID and a rental contract or an authorisation from someone registered at the address. It is free.
- No rent cap: the 2023 Housing Law lets regions declare 'zonas tensionadas' with capped rents, but the Comunidad de Madrid has not declared any, so the rent on a new contract is whatever you agree.
- Rooms and temporary contracts: rooms were often rented under the Civil Code, or on 'temporada' contracts, outside the LAU's protections. Real Decreto-ley 29/2026, in force since 8 October 2026, brings both under the LAU and requires a real, documented reason for a temporary contract, usually for at most 12 months. A decree has to be approved by parliament to stay in force, and that vote was still pending in early November 2026, so check its status on boe.es.
Scams and red flags in Madrid
High demand and many people searching from abroad make Madrid an easy target. Most scams ask for money before you have seen the room or met anyone.
- The owner who is 'abroad': a cheap, nice flat, a landlord who cannot show it, and keys sent by post after you pay by bank transfer or through a link that imitates Airbnb or Booking.
- Any deposit or 'reservation' asked before you have seen the room in person or on a live video call.
- 'Sin empadronamiento' or no contract at all: you may be unable to register, and it is harder to get your deposit back.
- A tenant subletting rooms: under the LAU a tenant can only sublet part of a flat with the landlord's written consent. Ask to see the main contract.
- 'Honorarios' or 'gastos de gestión' charged to you by an agency.
- To check: ask for the owner's name and compare it with a nota simple from the Registro de la Propiedad (you can order one online), search the photos and phone number online, and pay only by traceable transfer against a signed contract and a receipt.

Questions about renting in Madrid
How much does a room cost in Madrid?
About €575-700 a month. Idealista's 2025 average was about €575, and OCU's study of asking prices in August 2026 found €689, from about €459 in Águilas to €759 in Universidad (Malasaña).
Is there a rent cap in Madrid?
No. The 2023 Housing Law allows capped 'zonas tensionadas', but the Comunidad de Madrid has not declared any. Agency and contract fees still cannot be charged to the tenant anywhere in Spain.
When is the best time to look for a room in Madrid?
Demand peaks from July to September and in December and January, when Erasmus and other students arrive for each semester. Spring and late autumn are calmer, with more time to view and compare.
Can I register (empadronarme) in a rented room in Madrid?
Everyone who lives in Spain has to register in the padrón of the town where they live, and a landlord's refusal does not remove that duty. In practice it is much easier with a contract or an authorisation from someone registered at the address, so ask before you commit.
Is Roomly free?
Yes. Searching for apartments and roommates and posting a listing on Roomly are free.
