Trying to Visit Istanbul in 48 hours can be overwhelming. and if you haven't done your homework, look no further. Presenting best things to do and budget ways to breeze through Istanbul. Mind you, I am a little inclined towards history.
Airports & Public transport systems -
Istanbul has 2 airports, check out which one you arrive in.
> If its Istanbul Ataturk (IST), consider yourself lucky. Follow the sign board and make your way to the metro station in the basement. Your destination will be Sultan Ahmet Square. A combination of metro and tramway will take you there. Don't worry, its not aero-physics, you will find your way, the inter changing stop is smooth.
> On the other case if you find yourself in Sabiha Gokcen (SAW), hold your breath, its a little more than an hour's journey from the historic Istanbul center. Find your way to Havatas bus which starts from arrival level. You will have to get down in Taksim and then take an onward tram to Sultan Ahmet square.
In both cases you will need Istanbul Kart, a magnetic travel card that you can use across all the public transport systems in Istanbul. You will find yellow kiosks from which you can buy them for 7 Turkish Liras. Don't commit the mistake of getting the 5 Lira pass, it's for one time use and not rechargeable. Please use change, in my understanding, the kiosk credits whatever amount you put in, to the card.
