Europe’s largest open-air flea market runs every Sunday morning 9am–3pm in the La Latina neighborhood. Hundreds of stalls sell vintage toys, prints, and curiosities that fascinate older children. Streets are very crowded by 11am — arrive early and keep bags zipped. Combine with breakfast at a nearby café and explore La Latina’s tapas bars for lunch.
