Florence is compact enough to see the highlights in 2 days, but 3 days lets you breathe, eat properly, and add a Tuscan day trip that transforms the experience. The city is walkable (everything within 15min of the Duomo), the art density is the highest in the world, and the food — bistecca, lampredotto, Chianti by the glass — requires TIME, not just a lunch break between museums. 1 day? Possible but a crime against the Renaissance. 4-5 days? You'll start knowing the baristas by name and debating Brunelleschi vs Alberti with other visitors. That's the Florence sweet spot.
Plan my Florence trip →Day 1 — The Big 3: Accademia (David — book at uffizi.it, €16, arrive at opening. 30-45min). Walk to Duomo (exterior — the most elaborate facade in Europe. Climb the dome if you have a reservation: 463 steps, the frescoed interior, ALL of Florence below). Uffizi (book ahead — Botticelli Birth of Venus + Primavera, Leonardo, Raphael, Caravaggio. 2-3h for the highlights, don't try to see everything). Evening: cross Ponte Vecchio to Oltrarno — dinner in Piazza Santo Spirito (the real Florence). Day 2 — Deeper Florence: San Lorenzo market + Mercato Centrale (ground floor: traditional vendors. Upper floor: gourmet food court). Basilica di Santa Croce (Giotto frescoes, Michelangelo's tomb, Galileo's tomb). Afternoon: Piazzale Michelangelo (bus 12 or walk up — THE panoramic view of Florence. Go at 5pm for golden hour). Evening: aperitivo at a rooftop bar (SE·STO on Arno for Ponte Vecchio views), dinner in the San Frediano/Santo Spirito area.
Days 1-2: As above. Day 3 — Tuscan day trip: Option A: Siena (1.5h bus — the Campo, the Duomo, the medieval rival city. A full day easily). Option B: San Gimignano + Chianti (rent a car or join a tour — the towers + a wine tasting + the Tuscan landscape). Option C: Lucca (1.5h train — cycle the walls, the Torre Guinigi with trees, the oval piazza). This day trip is what transforms "I saw Florence" into "I understand Tuscany."
MONTHS ahead: Duomo dome climb (mandatory timed reservation at duomo.firenze.it). WEEKS ahead: Uffizi (uffizi.it — timed entry, especially morning slots). Accademia (same site). DAYS ahead: Restaurant reservations (Trattoria Mario for lunch, Da Burde for authentic). No booking: Ponte Vecchio, piazzas, churches (mostly free), Oltrarno walking, gelato.
