Twenty-three thousand voices against rental abuse in Madrid

Published on May 25, 2026 | Translated from Spanish

About 23,000 people, according to the organizers, took to the streets of Madrid to demand decent housing and denounce the abuses of the rentier system. The protest marched through the city center, uniting citizens of all ages against real estate speculation and unaffordable rental prices. Demonstrators called for urgent measures from the Government to regulate the market and guarantee the constitutional right to adequate housing, criticizing the lack of effective policies to curb the uncontrolled rise in prices.

Technology and data to analyze the rental bubble 📊

The rental market in Spain can be studied using data analysis and scraping tools. Platforms like Idealista or Fotocasa offer APIs and scripts that allow extracting historical prices by neighborhood. With Python and libraries such as Pandas or Matplotlib, it is possible to create trend charts and detect speculation patterns. For example, a time series analysis in central Madrid shows a 40% increase in five years. This data, accessible to developers, allows tenant associations to present technical reports supporting their demands for regulation.

The app for renting a shoebox 📦

Since an apartment in Madrid costs the same as a mid-range car, maybe it's time to develop an app for renting alternative spaces. Imagine the Minimalist studio section: a built-in closet with wifi for 800 euros per month. Or the Premium balcony option, with views of the asphalt and no elevator. Investors would be delighted: the price per square meter of a cardboard box in Sol would be the new bubble. While the Government regulates, we innovate. After all, the problem isn't housing, it's that we haven't yet optimized the portable home niche.
