Maresme is not one market. It is about thirty municipalities strung along the coast between Barcelona and the Costa Brava, and the price of the same four-bedroom villa can double within fifteen minutes of driving. If you are renting long term here, this is the short list of towns where the money goes furthest north of the city — and the honest reasons why.
Two things skew every Maresme price list. First, town averages mix a two-bedroom flat by the station with a six-bedroom villa on the hill, so the average tells you very little about what a family house costs. Second, most of these towns have a small, old core where prices are ordinary, and a handful of streets where they are not. The ranking below is about that upper end: the towns that command a premium for long-term villa rentals, ranked by how consistently they do it.
The quiet one at the top. Sant Vicenç sits on the hills between Sant Andreu de Llavaneres and Caldes d'Estrac, low-rise, almost no through traffic, and it has built a reputation as the town people move to when they no longer want to be seen. Plots are generous, the sea views from the upper streets are the real thing, and there is essentially no new apartment supply to dilute the market. Villas here rent as houses, not as square metres, which is why they top the list.
Llavaneres has the three things the top of this market pays for: Supermaresme, the gated hillside estate where the biggest houses in Maresme sit, a working marina at Port Balís, and a golf course just outside town. It also has a centre that feels like a town rather than a dormitory, with a market and schools. The combination of a real village and a genuinely exclusive estate is rare, and the rent reflects it.
Cabrils is the green one — steep streets, pine trees, plots that actually have gardens rather than a strip of gravel. There is no beach of its own and no train station, which used to keep prices down and now does the opposite, because the people who can afford a car are precisely the ones who want the privacy. The village centre is small and agreeable; most rentals are detached houses on the hill above it.
Cabrera de Mar climbed fast. It has the beach, the R1 line, the castle of Burriac on the hill above, and a mix of old village and newer urbanisations that gives it more variety than most of its neighbours. That variety is also why it is a little cheaper than the three towns above: a buyer or tenant here is not only paying for hillside exclusivity, and the market is broader as a result.
Alella is the closest of the premium towns to Barcelona — roughly twenty minutes by car when the C-32 behaves — and it wears its wine history openly: the DO Alella vineyards run right through the municipality, and some houses still sit next to working vines. It has no station of its own and no beach, so you trade convenience of the road for green hills and a genuinely old centre. Renters here are often Barcelona professionals who want a house and a garden without a forty-minute commute.
Both sit in the hills just above the coast, both are leafy and residential, and both are quietly expensive without ever being flashy. Teià leans on the Serralada Litoral park and its own wine tradition; Premià de Dalt has bigger plots and a slightly more suburban feel. They are the sensible premium choice: a fifteen-minute drive to the beach, a station on the R1 a short hop downhill, and prices that are high but a notch below the top five.
One warning about numbers. Any figure you read for these towns — average rent per square metre, average monthly rent — is dragged around by the mix of flats and houses, and by whether the agency included furnished short lets in the sample. Treat published averages as a direction, not a price. For a villa with a pool and a garden, the gap between the town average and what you will actually be asked to pay is often large.
