Istanbul lies on both sides of the Bosphorus, so it is a city in Europe and in Asia at the same time. Two airports serve it. Abbasi Travels can search flights to Istanbul for you and help with your questions.
Most guides recommend spring (April to May) and autumn (September to October), with moderate temperatures and clear days. July and August are hot and humid. Winter, December to February, is cooler and wetter and usually the quietest season. Figures differ between sources, so treat them as a rough guide.
