Nantes feels like “Trams everywhere since 1985, the Atlantic an hour west, and a city that still argues it is Breton”, while Sofiais “Ten per cent flat tax, a 2,290-metre mountain on the city bus route, and a euro that arrived in January 2026”. Climate is a real differentiator: Nantes — mild and oceanic — rarely cold, rarely hot, and grey with rain spread evenly across the year. Sofia — continental at 550 metres in a mountain basin — warm dry summers, real snow in winter, and cold still spells that trap the valley's air for days.
