The initial payment required for moving in consists of a security deposit amounting to three months' rent, along with two months' rent paid in advance, plus the rent for the first month. The rental contract is open-ended, without a specified termination date, and concludes only after a three-month notice period is given by the tenant. This notice must always commence on the first day of a month. For private tenants, the rental period is set at two years, whereas companies must commit to a minimum lease length of twelve months.
