San Niccolò is a district of contrasting vibes. Near the Arno the streets are lined with laid-back restaurants and wine bars, and in warm weather, locals set up parasols and deckchairs along a stretch of the riverbank. Closer to the hills, elegant villas set a more upscale tone. A path snakes through the Giardino Bardini park, climbing up to the 17th-century Villa Bardini, which has 2 museums and offers city views.
