Which one fits a couple
On the factors we measure, İzmir leads on cost (€2,488 against €2,624 a month), and Istanbul leads on none of them. What our data does not cover can still tip it toward Istanbul: jobs, family nearby, or simply which one each of you prefers after a visit.
Climate can pull the two of you apart too: a partner who wants warmth leans toward İzmir (18°C on average), while one who minds the heat leans toward Istanbul (16°C).
Size differs too: Istanbul is a major city (over 5 million people) and İzmir a large one (1 to 5 million people).
