A non-stop photo and souvenir opportunity, Trevi is all about action. From early morning through the wee hours, the piazza surrounding Trevi Fountain hosts a never-ending flow of tourists hoping to make a wish or take a selfie. Clever restaurants, charming gelaterias, uncanny bars, kitsch shops, and a range of hotels make up the local landscape. Beneath the bustle are the remains of an ancient neighborhood that you can visit by heading over to a repertoire cinema and asking for a peek underground. There is something for everyone, but if peace and quiet are what you seek, plan to visit in the early morning hours.
