Piazza Garibaldi is the main transport hub in Naples. The central train station, two subway lines, the Circumvesuviana train (a regional train to Pompeii, Herculaneum, Sorrento, etc.), a bus station, taxis, and several historic hotels are in the area around Piazza Garibaldi. Therefore, this is the best area to stay in Naples for one night in general. However, if you are planning to visit Capri, Ischia, or Amalfi after Naples, the Port of Naples might suit you best.
