Work / Cost of living in Warsaw with two kids [14]

Merged: Relocating to Warsaw with one kid family

Hello,
i have been offered a job in warsaw with 10000pln net per month. if i accept, iwill move with my husband and my son (almost 3 years old). assuming that my husband will not be able to find a job since the beginning, we wonder if my salary would be enough for a normal life and for a bit of savings. can you give some advice on the expenses?
