Ludovisi / Via Veneto
Thanks to Fellini and La Dolce Vita, the Ludovisi and Via Veneto neighborhood earned its reputation as a posh area where gorgeous Marcellos wooed actresses and models while bored housewives hung out in streetside cafes. The cafes are still there, and so are the cocktails, but the neighborhood is now home to five-star businesses including hotels, banks, law firms, and embassies. The area is also right next to Villa Borghese, a beautiful park for sporting and cultural adventures. If you're looking for tranquility by night, this may be the place: Ludovisi and Veneto tend to shut down after 8pm.
