I am shocked how historically interesting the city, the former Constantinople, sights are at every turn. it’s important to download an audio guide for a few days, because there you will be offered excursions for $ 85, and upon arrival you can buy a transport card for 20 lira, you can use it to travel by tram, metro, bus, ferry, and every next trip per day with a price reduction. We passed 20 objects a day and were very pleased and especially liked the central part, Galata and the fortress of Rumelia Hamar by ferry. We also want to go back there. As for prices, not at all expensive and street cafes and fish restaurants on the Galata bridge, quite a civil service, very tasty and voluminous portions. I advise everyone to an unusual historical fabulous Istanbul, but write out a list of a lot of things to see!
