Brussels feels like “Capital of the EU and a bilingual region of its own — nineteen communes, each with its own tax rate”, while Lyonis “France's second economy, a rent cap that is actually enforceable, and the Alps ninety minutes east”. Climate is a real differentiator: Brussels — grey, wet and rarely extreme — rain most weeks of the year, mild winters, and summers that only occasionally break 30°c. Lyon — semi-continental — cold winters, hot summers, and a distinct spring and autumn. more extreme than coastal france in both directions.
