The driver needs to be at least 20 years old when renting a budget vehicle and 21 for comfort and luxury vehicles. Another requirement is that the driver must have a valid driving license and must have held their driving licence for at least one year. You do not need to have an international driving license, although that is preferred. However, the information on your license needs to be written in the Latin/Roman alphabet, and you will need to carry it with you at all times, not a copy. Rental agencies often require a credit card in the name of the driver as well.
