Italian law is strongly pro-tenant

Rents: Rents can initially be freely negotiated, but increases are restricted. Landlords can only increase the rent after the initial 4-year contract.

Tenant Security: Tenants have the right to controlled rents, and effectively eight years or more of security of tenure. A landlord may only serve a disdetta - a registered letter of notice which must be sent at least six months before contract expiry - to coincide with the end of the standard 4 years. Failure to do so automatically renews the contract for another 4 years.

This is such a disadvantage to the landlord, don't you think?
But then for those who plan to rent in Italy it means a lot.
