Italy Costs Associated with AirBnB

Does anyone in this FORUM rent our properties in Italy?

I am from UK moving to Italy for 6 months initially and wanted to rent a large apartment with a view to renting out a spare room to help cover the rent. If it works well I hope to buy and settle there.

IS IVA chargeable on rent received? I know it is chargeable on services but it is also charged on rent?

Any guidance of other issues re renting out rooms in Italy would be welcome.

Thanks
