The tenant has the right to have the property delivered in good condition by the landlord.
Furthermore, the tenant has the right to require from the landlord to keep the place in a state that is suitable for the use agreed by the two parties for all the term of the contract.
Unless otherwise agreed between the parties, the tenant is only responsible for “ordinary’ maintenance of the apartment: “ordinary maintenance” consists of minor repairs aimed at keeping the systems or parts of the property efficient. For example, repair of the boiler or periodic servicing and repair of the electric shutters or of the washing machine.
Always unless otherwise agreed between the parties, the agreement provides that extraordinary maintenance is entirely the responsibility of the landlord (e.g., replacement of an old boiler and of the roller for electric shutters or replacement of the washing machine).
If the repairs are urgent, the renter will be able to proceed directly, subject to reimbursement (however, remembering to notify the lessor if the repairs were up to him).
