Barcelona Rent

Current average rent and sale price for one Barcelona neighbourhood or district, from contracts actually registered with the Catalan government — not listing or asking prices. Accepts a neighbourhood name, a district name or a URL slug. Returns euros per m² per month, an estimated monthly rent for a reference flat, the sale price per m², gross rental yield where both figures describe the same quarter, and the quarter each figure comes from.

The quarterly series of registered rents for one Barcelona neighbourhood or district, and how much it has changed over the window. Use for questions about whether rents are rising or falling in a specific area. Figures run from 2014 for neighbourhoods and 2000 for districts.

Which Barcelona neighbourhoods a monthly budget actually reaches, cheapest first, based on registered rents rather than advertised prices. Use when someone says what they can afford and wants to know where to look.

What a Barcelona neighbourhood is actually like, from the city's own published measures: how much street commerce it has, how much road traffic noise reaches residents at night, how steep its streets are, how many households have a child, and how many residents hold a foreign passport. Each figure comes with the city median and the barri's percentile among all 73. Use for questions about whether somewhere is quiet, lively, hilly, family-heavy or international — not for questions about price. None of these explains what a barri costs.
