Welcome to Istanbul! As someone who lives here and often drives guests around, I'll say right away that our famous Bosphorus Bridge is a whole other story during rush hour. You can get stuck there for a long time, so for a trip like this, it's best to have an experienced driver who knows the city and alternative routes well. I often take this route myself and long ago switched to the transfer aeropuerto Estambul SAW via GetTransfer. The price is fixed before the trip, and all fees and tolls are included. The ride to Sultanahmet costs around 900–1,000 lira, with no additional charges. The driver will meet you at the terminal, help with your luggage, and take you directly to your hotel on the European side.
