Work / Average salary in Poland for PhD in IT [40]

Question - I have my Masters in IT, MCSE, CCNA, CFOI, PMP, ITIL V3 and have been presented and offer in Poznan for 186,907.50 PLN before takes per year. I will also receive an expat package to include a car and partial housing assistance? As I have never lived in poland (Lived in Moscow, Minsk, Budapest, UAE and other locations) is this a fair contract?

Any guidance and direction you can provide would be a great help.
