There isn't usually a problem with paying your landlord via Banco di Napoli, I have been doing this for 15 months. Getting money to them was very difficult. If you need an Banco account just take your passport, orders, Codefiscale and ID card to JFC or Capo and open one, very easy. Additionally, I wonder how long it will take the Housing Office to abide by these regulations as I hear they are waiting for a different interpretation (or one that suits them). Every house should be properly listed with the housing office, but we know what goes on behind the scenes. Will this law be enforced and the threats become reality? only time will tell, but I think that this won't happen. Maybe I am just jaded by see the Neopolitan way of doing business, we will see in time if the law is adhered to by everyone, not just those foreign renters...
