If you've decided to stay in Naples then this is a fantastic place to make your base. Great high ceilings within a traditional style Naples block and a fantastic roof terrace. It's a 10 minute walk to the main train and metro station (Garibaldi), where you can go to Pompeii, Sorrento etc. You can use the metro to the port and get the hydrofoil to Sorrent or Capri.
Naples is not to everyone's taste and is quite rundown in places and the roads are a law unto themselves so do you research first.
