Grenoble feels like “Europe's chip and big-science cluster on a flat valley floor, three mountain ranges deep — and France's steepest property tax”, while Nantesis “Trams everywhere since 1985, the Atlantic an hour west, and a city that still argues it is Breton”. Climate is a real differentiator: Grenoble — semi-continental in a mountain valley — cold winters with temperature inversions that trap the air, hot still summers, and a sharp short spring and autumn. Nantes — mild and oceanic — rarely cold, rarely hot, and grey with rain spread evenly across the year.
