Three days minimum, five ideal. From the Colosseum to the Vatican, from the Pantheon to Trastevere: 28 centuries of layered history packed into a centre you can walk.
Rome works best when visited by area, not by checklist. The archaeological core (Colosseum–Forum–Palatine) takes a solid half-day. The Vatican, across the Tiber, eats a full day between Museums and Basilica. The historic centre — Pantheon, Trevi, Navona, Spanish Steps — covers in an afternoon on foot. Trastevere is for the evening. Everything fits within 3-4 km, but summer heat and crowds double your timings. Distances are deceptive: from the Vatican to the Colosseum it's a 30-minute walk under the July sun, or two metro stops (A+B with a change at Termini).
Rome was founded on 21 April 753 BC according to the legend of Romulus and Remus; excavations on the Palatine confirm 8th-century BC settlements. Four centuries of monarchy, then five of oligarchic republic, finally — from 27 BC under Augustus — the centre of an empire stretching from Britain to Egypt. In the 2nd century AD it housed about one million inhabitants, a figure Europe would not see again until the 19th century. After the fall of the Western empire in 476, the city emptied: by the early Middle Ages just twenty thousand remained. Rebirth came with the 15th-century popes: Nicholas V, Julius II and Leo X commissioned Bramante, Michelangelo and Raphael to build the new St Peter's, the Sistine Chapel and Bernini's squares. On 20 September 1870 General Cadorna's troops entered through Porta Pia and Rome became capital of the Kingdom of Italy. Today three Romes overlap — ancient, papal, modern — visible within 500 metres of Via dei Fori Imperiali.
April-May and September-October are the best months: 18-25°C, long daylight, manageable queues. April also brings Rome's Birthday (21 April) and Easter, with papal ceremonies at St Peter's filling the city. June-August is peak summer (28-35°C, peaks of 40°C in August): heat and humidity make open sites like the Forum and Palatine punishing, but evenings are long and packed with events (Estate Romana). Flights are most expensive between July and mid-August. November-March is low season: rain in November, 5-15°C between December and February, but short queues at museums and flights from €30-50 from Milan or Naples. December is popular for Christmas (nativity displays, Piazza Navona markets) but weather is unpredictable. Avoid mid-August (Ferragosto) if you want traditional trattorias: many shut.

Roman cuisine is poor man's food, built on offal and the "fifth quarter". The five pasta pillars: carbonara, cacio e pepe, amatriciana, gricia and pajata. Mains: saltimbocca, slow-roast lamb, oxtail (coda alla vaccinara), tripe. Starters: supplì (€2-3), fried courgette flowers, Jewish-style artichokes. Roman pizza is thin and crisp (by weight €8-12/kg), different from Neapolitan. For honest prices and quality: historic trattorias in Testaccio (Felice, Flavio al Velavevodetto, Perilli — lunch €25-35), Trastevere (Da Enzo al 29, Da Lucia), Monti (La Carbonara, Taverna dei Fori Imperiali). Avoid set tourist menus near the major sights (€15-20 with overcooked pasta). Gelato: Giolitti (since 1900), Fatamorgana for unusual flavours, Gelateria del Teatro. Coffee €1-1.20 at the counter, €3-5 sitting down in central squares.
Historic centre (Pantheon-Navona-Trevi-Campo de' Fiori): tourist heart, walkable in half a day, high prices, always crowded. Trastevere: across the Tiber, medieval alleys, authentic trattorias, young nightlife (gentrifying fast). Monti: between the Colosseum and Termini, vintage boutiques, cocktail bars, considered restaurants. Testaccio: the food district par excellence — covered market 8:00-14:00, historic trattorias, nightlife at the former slaughterhouse. Prati: next to the Vatican, ordered and middle-class, great for sleeping (3-star €80-120) while staying near the centre. Coppedè: small Art Nouveau gem north of the centre, off the tourist trail, 20 minutes on foot from Villa Borghese. EUR: 1940s rationalist district, monumental architecture, parks, far from the centre (15 minutes on metro B).
