People arrive for a six-week treatment, a two-year posting at a hospital, or a relative in intensive care, and they need a flat by Thursday. This is how that rental actually works, and where it goes wrong.
Sant Joan de Déu, in Esplugues de Llobregat, is the children's hospital for a large part of Spain and the one that produces the most short family rentals. Vall d'Hebron, on the northern edge of the city, is the big general and transplant centre. Hospital Clínic sits in Eixample, Hospital del Mar down by the port, and Germans Trias i Pujol — Can Ruti to everybody — out in Badalona. Add Parc Taulí in Sabadell for the Vallès side.
Transport decides where you sleep. Sant Joan de Déu has the Trambaix (T1, T2, T3) stopping by the hospital and Metro L5 at Can Vidalet a short walk away; Vall d'Hebron has L3 and L5; Clínic has L5; Hospital del Mar has L4. If you will be there every day for two months, a 25-minute walk in July is not the same walk as in January.
Sant Joan de Déu keeps an accommodation page for families, listing nearby hotels, apartments and temporary-stay services, with a blunt warning that the hospital is not affiliated with any of them and that you book directly. It quotes doubles at roughly €60–300 a night depending on category. Read that page before you accept the first WhatsApp offer forwarded in a parents' group: at least it is a list the hospital maintains itself, and it will not disappear with the phone number.
Under 32 nights it is a tourist let and the property has to have a HUT licence. Over 31 days it is an arrendamiento de temporada, and that is where hospital stays normally land: a stated cause, twelve months maximum, furniture included. Medical treatment is exactly the kind of cause the law expects, so a three- or six-month contract is normal and legitimate. What it is not is a five-year vivienda lease — do not sign one thinking you can walk away in eight weeks.
Since 2025 the cause has to be credible. A contract that says 'temporary' with no reason, or a tenant who stays two years as if it were home, can be reclassified as a vivienda lease. If you are arriving for treatment, that is not a problem for you — you have the letter. It is exactly why the owner will ask for it.
Around Sant Joan de Déu the practical belt is Esplugues itself, the Barcelona side of Les Corts and the Zona Universitària edge. A furnished two-bedroom in Esplugues runs roughly €1,300–1,900 a month; in Les Corts, €1,400–1,900. The houses up in Ciutat Diagonal, five minutes from the hospital, start around €2,600 and climb past €6,000.
Around Vall d'Hebron, Horta-Guinardó is the value play: €1,050–1,400 for two bedrooms, bigger flats than the centre, hospital on L3 or L5. Clínic pushes you into Eixample at €1,500–2,300, convenient and loud. Can Ruti means Badalona at €900–1,400. Parc Taulí means Sabadell, a little less again, with a longer ride if you also need the city.
Then the running costs: €120–200 a month of electricity in a normal flat, more in winter if the heating is electric, and a deposit legally capped at three months in total — one month fianza plus up to two of additional guarantee.
Without Spanish payslips the pack is: passport, NIE if you have one, the hospital letter or the employment contract, six to twelve months of bank statements, and often the first months paid up front. A guarantor in Spain settles most conversations. If you are paying from abroad, a SEPA transfer in euros is normal and cheap; paying a deposit by card is not.
Ask for a factura every month, with the owner's NIF. If your insurer or your employer is reimbursing the accommodation, the invoice is the difference between getting the money back and not. Keep the signed lease as well — some insurers ask for it, and so does the tax office if you claim anything.
Can we rent for six weeks? Yes — six weeks is 42 nights, so it is a temporada contract, not a tourist let, and that is the cleaner product. A week or two is a different story and needs a licensed HUT property.
Do we need an NIE? Not to sign a lease. You need identification, and you will want the NIE soon for the bank, the utilities and the school. Some owners ask for it up front; most accept a passport plus the hospital or work letter.
Is a hotel cheaper? For two weeks, sometimes: €90 a night is €1,260 a fortnight, and a flat is €1,300–1,900 a month plus bills. From about three weeks the flat wins, and you get a kitchen, a washing machine and a door you can close.
Can the landlord end it early? A temporada contract ends on the date written in it. The owner cannot normally cut it short without cause, and you cannot walk away without the penalty the contract sets. Read that clause twice, because it is the one that costs money.
One honest note to finish. Owners and agents in Esplugues and Les Corts know exactly why the phone rings in February. The good furnished flats near the hospital go in days, not weeks, and the ones that sit for a month are usually sitting for a reason — a fourth floor, a dark living room, a boiler from 1998.
