Any idea on what bus to take from the airport to Sultanahmet area at 8pm
Do a google search for the Havas bus.
Thanks. Checked with Havas and found also the airport shuttle that takes you for Euros 20 from the Sabiha Gokcen Airport to a hotel in Sultanahmet .
That sounds awfully expensive. Looking at the website the bus only costs TL10 to Taksim. Not sure if there is a bus to Sultanhamet directly, but you can easily connect in Taksim if you want to save some money.
