It seems that the areas around the main train station is where the thugs, homeless, thiefs and fake/stolen goods sales is being done, which makes the area not safe to live in. Next time I’ll choose a stay in a safe area, like the tourist neighborhoods or Vomero.
The main issue with the flat was that the listing was inaccurate. There was supposed to be 2 proper beds and 2 sofa beds. But it only has 1 bed and 1 sofa bed (which was too soft to sleep on).
The flat itself is looking good and is newly rebuilt, however some things are still old like the door which does not block out the noise from the staircase/outside/neighbors.
This apartment could be good for those that will only use the bed, and must stay close to the train station and can handle unsafe neighborhoods. But for our purposes this was not a good fit.
