Living and working (Kyiv)

Hi, am looking into a job proposal in Kiev. Have seen posts on this forum but no specific answers so here it goes:
can someone let me know what are prices for renting a flat ~ 50sqm?
what are avg salaries for a management positions at top level?
how are the driving conditions outside big cities, like Kiev?
is the current economic climate stable, in view of the ever-discussed crises?

be much obliged for at least some direction where to look for this info

manythanks
