Property for Sale in Castelldefels

real estate in Castelldefels, Baix Llobregat

Castelldefels is a coastal town on the Baix Llobregat, about twenty kilometres from Barcelona and fifteen from Sitges. It has five kilometres of beach, a direct train to the city, and a British School of Barcelona campus, which is why many international families settle here.

The town divides between the beach, where the streets run back from five kilometres of open sand, and the older centre inland below the castle. Between them sit the residential slopes of Bellamar, Montemar and Vista Alegre, where most of the villa stock is.

The draw for international families is usually practical rather than scenic. The British School of Barcelona has a campus here, El Prat airport is about ten minutes away, and the R2 Sud line runs into Barcelona Sants in roughly twenty-five minutes. The C-32 reaches Sitges in a quarter of an hour along the Garraf coast.

Property runs from beachside apartments to detached villas on the hill, and the price difference between a street near the sand and one on the slope is significant.

What makes Castelldefels exceptional

Between two markets

Twenty minutes to Barcelona, fifteen to Sitges, on the C-32 and the R2 Sud line.

Who it suits
