Cost of living

Hi
We will be moving to Helsinki in Feb 2015. Salary of my husband will be approximately 3811 Euro per month. I have a kid 2 yrs old. Just want to know whether the salary amount is sufficient for 3 of us to live in Helsinki and please guide me regarding the accommodation available there.
Thanks
