HI,Very difficult to say.All journeys are on the meter,and I do not know the mileage rate off hand .You will not be ripped of!ensure the meter is on!at the beginning of the journey and use a cab from Koca calis,otherwise you will pay for the journey from calis to you!When you have experienced it once then you can negotiate the price for the future.But, be aware you cannot do private hire here,the taxi must have his meter on for the police/gendarma!.I suggest you use one one from the calis traffic island to Koca calis first and take it from there for a future deal,if you get my drift.
