Standard in Turkey is 2x double offs and the rest as single offs, every month. Sometimes they can group a couple of more days off but on the short haul forget about commuting.
They use basic ICAO ftl with many exemptions. Fatigue is a great problem and expect no free time. You will fly from both İst and SAW. Travelling between the two can sometimes take three hours, not taken into consideration for FTL, also standby days are not even counted as duty time. Not even if you are called in on that day etc. Turkish dgca keeps approving dodgier and dodgier FTL exemptions.
Accommodation is a little cheaper than in western Europe but expect at least a thousand euros a month for somewhere semi decent unfurnished.
