You will most probably arrive in Isfahan by bus.
Make sure you get off at ‘Kaveh’ bus terminal(not ‘Sofeh’) as it’s super close to the apartment. Then you can either :
1-Take a taxi )costs less than 2 dollars)show the driver the address in Farsi : کاوه،خیابان پنج آذر،انتهای کوچه شماره ۴، مجتمع تندیس،واحد ۱۶
2-On foot (not recommended but doable) : you can walk from ‘Kaveh’ bus terminal to the apartment and it takes about 20 minutes.
