Being Offered a salary of €70,000 to move to Ireland, is it worth it?

So I am very big on savings and investments, that being said, I am considering if I should turn down the offer, this is based on my concern around the taxes and the cost of rent, I used an income calculator and it seems my take home would be €3571 after taxes and pension contribution (firm said they'll match it up to 7%), I'll like to live alone, I'm 30 and I have never lived alone before and the cost of rent i am seeing is quite scary, up to €2200 for a single bedroom, excluding utilities, I guess my concern is if I should reduce my pension and maximize my net income so I would have enough leway to save or just suck it up and manage my net income after tax.
