What is a decent salary in Poland?

I've been offered a job in Wroclaw that pays 7,450 zloty gross (approx. 5,255 NET). Is that enough for a single person to live on? I want to be able to have a decent flat and spare money for fun stuff etc. Thanks for any advice! :)

Should be ok, I live in Jelenia Gora, not far from Wroclaw, so could meet you there one day :-)

What is your job position?
