Roberto's place is located at a stone's throw from Napoli centrale/Garibaldi (not literally but felt like that ☺).
The apartment is small & cozy, ideal if ur need is just B&B & if u plan staying in Naples to visit other attractions closeby. Googlemaps link from airbnb is incorrect so follow the one he sends u (not his fault as airbnb needs to fix this).
He is an awesome host & accommodated multiple unforseen delays from our end with a smile. Go for it if all u need is a nice place to sleep, freshen up & catch the next train without wondering when u could return coz all u will need is to walk back to the apartment from the station.
