Where do these figures come from?
The €/m² range comes from the average asking rent published by Idealista (September 2026). Rents by size are calculated with the same model as our analysis tool: the published price of the area (or sub-area, capped at the district average in Madrid and Barcelona), adjusted for size, because small flats rent for more per m². These are asking rents from listings (unfurnished, long term), not signed rents. The low end is not a floor: adjust for condition, floor, terrace or parking.
