I’m primarily interested in the logistics of getting from the airport to the city center—the best way to get there, how long the trip takes, and whether there are any pitfalls to avoid. I also want to understand how to navigate between the two airports, since I see that tickets are sometimes offered through Sabiha Gökçen, which is on the other side of the city. I’m also curious about currency—should I exchange money in advance, or is it better to withdraw lira once I’m there? And do tourists need a visa, or can I fly without preparing any documents?
