The Renaissance capital at maximum density: 4.65 million international arrivals into a five-square-kilometre core, Italy's highest tourist-tax take, a record airport on a short runway — and a luxury hotel wave betting on quality over volume. Five studies, one hub.
Florence enters the TIO metropolis series as Europe's most concentrated tourism economy: 6.2 million visitors and ~12.8 million overnight stays a year pressed into a historic centre of five square kilometres that absorbs 95% of flows — 362,000 residents, 44,000 daily visitors on average, 80,000+ on peak summer days.
The gateways are straining and growing: Amerigo Vespucci closed 2025 at a record 3.85 million passengers (+9.4%), 87% international, while a €500-million-plus terminal and a rotated runway push capacity toward 5.9 million by 2035. Santa Maria Novella anchors the Frecciarossa spine — Rome in 1h30, Milan in 1h55 — and Tuscany's regional web turns Pisa, Siena and Lucca into day trips.
The money response is luxury: Italy's hotel investment hit €2.5 billion in 2025 (+19%), the four great cities taking 55% — and Florence's answer is palazzo conversions, from the reopened Villa San Michele Belmond to La Réserve's six-residence debut and Palazzo Morrocchi's Macchiaioli café reborn. Tourist-tax revenue: €76.9 million, the highest in Italy, above Milan and Venice.
