Dont forget to come to Asian side much cheaper then European side. Hop onto ferry from Karakoy or Besiktas or Eminonue to Uskudar for 2.60 lira its about 10-15 mins ferry ride and explore the beauty of Uskudar stroll along Kiz Kulesi |Maiden Tower pier. Enjoy the fresh homemade food in the restaurants and cafetarias/ Try the stuffed cabbage and vine leaves and tripe soup, try  the traditional hamam for 100 lira . Visit the old ottoman mosques and fish market. Shopping in Kadikoy just a 10 mins bus ride from Uskudar. From Kadikoy you can take a ferry to Princes Island and visit the old city.
