When the tenant terminates the tenancy agreemetn, the period of notice is one month.

It is common for a landlord to require that the tenant purchase insurance on the apartment.
Rent and utility charges are to be paid in advance once a month to an account provided by the landlord.
Any procedure for adjusting the rent must be agreed upon when drawing up the tenancy agreement. The tenancy agreement must also state the basis on which the rent may be increased and the landlord must provide advance written notice of the rent increase.
Normally, a tenant is not entitled to transfer his tenancy agreement to another party.
