I'm travelling to Istanbul in few days and have the day free to do some sightseeing. I need a safe place to leave my luggage while I'm out and about. I won't be staying overnight so I can't leave it in my hotel room. Any suggestions? I'll be arriving at Ataturk Airport in the early morning and leaving via an IDO ferry in the evening.
I suggest you also post your question at www.flyertalk.com. You will find an even larger audience. Good luck to you!!
