Soon my wife will join me so I'm little busy calculating monthly costs but it would be very helpful to receive your opinions

My after-tax salary is around 2700 eur, I'm planning to live in Vantaa, My wife won't be working for several months, so that would be our only income.
Do you think this is enough for a decent life? And what would be the maximum rent without compromising on food and going out once per week? And generally, economic wise, do you prefer public transportation or a car?
Thanks a lot
