Rome is 22 rioni (historic districts) and each one is a personality. Monti is the hipster with vintage shops. Trastevere is the loud, beautiful friend everyone follows. Testaccio is the chef who doesn't Instagram but cooks the best meal of your life. Where you stay, eat, and drink in Rome matters more than WHAT you see — because the Colosseum looks the same from every angle, but carbonara at Roscioli vs carbonara near the Trevi Fountain is the difference between religion and fast food.
Monti — Rome's hippest rione. Vintage shops, wine bars, Piazza Madonna dei Monti (aperitivo on the fountain steps). Best for: couples, solo travelers, first-timers who want walkable access to Colosseum + nightlife. Stay: boutique B&Bs €80-150. Eat: Ai Tre Scalini, La Taverna dei Fori Imperiali.
Trastevere — ivy-covered alleys, live music, the loudest neighborhood at night. Best for: nightlife, atmosphere, the "movie Rome" experience.

Centro Storico (Pantheon/Navona/Trevi) — the ancient heart. Walk-everywhere location. Warning: most expensive, noisiest, worst restaurant-to-tourist ratio.
