You will be centrally located - a two or three minute walk from Toledo Station. From this point, you can comfortably walk to many destinations, and public transportation is available for most everything else. I took the Circumvesuviana line to visit Pompeii and Ercolano. What I most enjoyed was just walking around the city and discovering the beauty of Naples. It was also great to just relax in one of the many piazze to enjoy a snack and people watch. Underground Naples was a 20 minute walk from the apartment. Great food, beautiful churches, museums, history, architecture, and people make this a trip worth taking. Have fun!
