The house is located on the street leading from Napoli Centrale. The apartment is on the 11th floor, it is bright and comfortable. There's no central heating but you can use air conditioner in heating mode.
Roberto was a very hospitable host and told me briefly about some places to visit and some restaurants (Tandem is good and Gambrinus is truly great!). There was no any problems with check-in or check-out.
A good place to stay!
