Nowadays many homes Italy have Internet connection. It is a good idea to ask your landlord or real estate agent about Internet availability when you enquire about a room/apartment for rent. The cost of the Internet connection is usually included in the rental rate. In other cases you may have to activate an Internet connection at your own expense and always with the consent of your landlord. There are several Internet providers in Italy (Alice, Libero, Fastweb, Tiscali etc.) that offer competitive subscription packages. For this kind of subscription you will need to show the sales representative your rental contract as well as your tax identification code (codice fiscal) and a valid photo ID.
If you are not going to stay in Rome for a long time, it may be cheaper and easier to activate mobile broadband Internet access through one of the phone companies.
In this case you will need to provide your Tax identification code and a valid ID.
