I recently visited Istanbul and Canakkale as research for a book, mostly for Australians and New Zealanders. I unfortunately missed some information and now hope someone can answer it for me. Any answers would be appreciated, thanks.
1) Directions from Istanbul airport (hire care parking) to get on to road to Tekirdag if driving a hire car
2) Cost of a taxi fare from Istanbul airport to Sultanahmet & / or Taksim.
3) Cost of taxi fare from Istanbul's Büyük Otogar (Main Bus Terminal) to / from airport
4) Rip offs people experienced (eg. with Taxis)-
