When you come off the Centrale station. It is gritty. Very touristy feels like the main train station in Paris. Grafitti and people hawking goods. Don't worry. You will be greeted by an amazing host who will have maps and tips and walk you through the neighborhood. He will contact you through what's app so if you need a question answers he tries to help. We want to go to a museum. Gave use directions on the train. He is what makes this place so special. The pictures represent the place honestly. There are markets and vendors around if you want groceries etc. I had a fun adventure in Napoli
