IST suits a north-western route after your Istanbul stay. Compare a later city collection with holding a car during sightseeing, and distinguish IST from Sabiha Gökçen SAW.
Enterprise’s IST international-terminal instructions place its counter in the terminal rental facility without a shuttle. This is that supplier’s arrangement, not a promise for every airport-labelled offer. Confirm your terminal, voucher address and return entrance.
A rental car is useful for regional journeys along the Aegean and Mediterranean coasts or for a separately planned Cappadocia stay. For central Istanbul, compare public transport and collect the car after your city days instead of paying to park it throughout the visit.
Compare airport collection with a later collection if you start with a city stay. Include the transport to a different rental branch and any extra parking nights when comparing the total cost.
