Istanbul is well connected through public transport that ranges from buses, trams and ferries. You also have the option of opting for cabs. The best option would be to get the Istanbul Kart as it can be used on buses, trams and the ferries. This is important if you plan on using public transportation throughout the city. You can find these cards in all major tram and bus stations in a kiosk.
Where to stay? Sultanahmet or Taksim Square?
This is a common question most people who travel to Istanbul have. If you want to stay at a place that is close to all the important attractions and has easy connectivity through public transport, then choose to stay in Sultanahmet.
However, if you’d like to party and want to enjoy the night life, then Taksim Square/Beyoglu is the place for you.
