Castelldefels
Castelldefels is a town twenty kilometres south-west of Barcelona, with around sixty-nine thousand residents. A tenth-century castle stands on the hill above and gave the place its name, and below runs five kilometres of sandy beach, among the widest near Barcelona.
For anyone moving this is a suburb of the Catalan capital with the sea attached: twenty-five minutes to the centre by train, ten to El Prat airport. Hence the price — the square metre here is among the dearest on the mainland coast, just below Barcelona's and above Marbella's. The town works all year, with visitors added in summer. Beside it lies the Garraf nature park, limestone hills right behind the buildings.

- Sitges · 18 km — the resort town beyond the Garraf hills
- Garraf · 10 km — the limestone hills and nature park
Castelldefels sits in Baix Llobregat, Barcelona, 1 km from the water. You can live here without a car: our rating is 5 out of 5, rare on the Spanish coast, and the town has its own train station. The airport is 15 minutes away, closer than for most places in the database. Fast internet at a median of 520 Mbps: remote work is not a problem here.

Castelldefels beaches and water quality
sourceCastelldefels has 3 beaches tested under EU bathing water rules, at 4 sampling points. In the 2025 season, all 3 were graded excellent. The last “poor” grade here was in 1990: Playa de les Lluminetes, Playa del Baixador and Playa de la Pineda.
The grade is bacteria in water samples over the last four seasons — not sand, views or crowds. “Poor” means bathing there is advised against.
| Beach | From the centre | Grade 2025 | “Excellent” in a row | Last “poor” |
|---|---|---|---|---|
| Playa de les Lluminetes | 2.2 km | excellent | 33 seasons | 1990 |
| Playa del Baixador | 2.4 km | excellent | 30 seasons | 1990 |
| Playa de la Pineda | 2.6 km | excellent | 21 seasons | 1990 |

What tenants actually pay
sourcedThis is the median rent on active leases — tax records for 2024, a sample of 4 895 leases. It includes long-standing contracts at unchanged rents, so it sits below what is asked today: our estimate of asking rent is 1 550 € for a two-bedroom.
The point of the 75th percentile: it is closer to what is being signed now than the median. The gap between them shows how much a new tenant overpays relative to long-standing ones.

Rent by number of bedrooms
asking price, estimate| 1 bedroom | 1 150 €/mo | |
| 2 bedrooms | 1 550 €/mo | |

Asking prices are what long lets are advertised at today; the registry is what tenants pay on signed leases, including old ones. The gap between them is your negotiating argument.

Renting without a Spanish contract
How realistic a long lease is without a nómina — on foreign income, savings or prepayment.
- —A community with its own services: agencies have dealt with foreigners before
- —Prices rising 8.5% a year — the landlord picks, and the first filter is a nómina
This is our model, not a measurement: demanding a nómina is an individual landlord's practice and nobody publishes it. The rating is derived from the share of foreign residents, the presence of a community with services, price growth, seasonality of the stock and the size of the town.

- International schools: where a family has a choiceSchool decides the town more firmly than price. What is counted is the choice, not the quality — we have no honest ranking and cannot build one.
- The coast without a carA resort stretched along a highway and an old port with a dense centre are different ways of living. Size is not what separates them.
- Where property is cheapest on the Spanish coast, on a single price basisThe housing ministry's appraised value, ranked by coast and by town, with the price of a 70 m² flat and local incomes alongside. Asking prices get a list of their own: the two bases never share a ranking.
