How Long Do You Actually Need
Cover what a long weekend gets you vs. a full week. Three nights means the Colosseum, the Vatican, and one good neighbourhood. Five nights means you can slow down, eat properly, and start to understand the city rather than just photograph it. Make the case for at least five nights. Note that most people underestimate Rome's walking distances and overestimate how many major sites they can cover in a day.
When to Go
Break down the seasons honestly. April–June is the sweet spot — warm, flowering, the light extraordinary. July and August are crowded and hot but manageable with early starts. September–October rivals spring. November–March is cold and quiet with the shortest queues. Address the Easter question: extraordinary atmosphere, enormous crowds, book months ahead or avoid.
Where to Stay: Neighbourhood by Neighbourhood
Walk through the main areas. The historic centre (near Campo de' Fiori, Navona) is central but loud and expensive. Trastevere is atmospheric but fills with nightlife crowds. Prati (near the Vatican) is quiet, local, and well-connected. Testaccio is the underrated choice for food. Link out to the neighbourhood pages. Warn against anything near Termini station unless budget is the only priority.
What to Book in Advance — and How Far Ahead
The list: the Vatican Museums (weeks ahead in spring, months in summer), the Colosseum (always advance), the Borghese Gallery (mandatory — strictly limited entry). What doesn't require booking: the Forum and Palatine Hill, most churches, the Capitoline Museums on a weekday. The rule of thumb: anything with a queue visible from outside the building needs a pre-booked slot.
Getting Around
Rome is best on foot within the historic centre. Cover the Metro (two useful lines, A and B), the buses (useful but confusing), and taxis (cheap, metered, reliable). Address the ZTL restricted traffic zone for anyone considering renting a car — don't. Day trips worth doing: Ostia Antica by Metro, the Castelli Romani by bus, Orvieto by train.
What to Eat and Where to Find It
The Roman canon: cacio e pepe, carbonara, supplì, carciofi alla romana. Where to find each honestly — not the restaurants that appear first in search results. The market at Testaccio. The difference between a real trattoria and a tourist trap (handwritten menu, no photographs, a full room of locals). How to find the right gelato (short ingredient list, no fluorescent colours). Link to the Testaccio neighbourhood page.
Practical Tips Worth Knowing
The things that aren't in most guides: the free entry to major churches (St Peter's, Santa Maria Maggiore, San Giovanni in Laterano — all free, all extraordinary). Carrying cash. The tabaccheria as the most useful shop in Rome. What the combined Forum/Palatine ticket covers. Why Tuesday and Wednesday are the quietest days at most sites.
