If it is 1200 euros, after tax to could just survive on that.
Expect 500 euros for an apartment (you will need 2 month deposit and 1 months upfront payment minimum), 300+/- euros on food and drink. 90 +/- euros electricity and water +/-, the rest depends on what else you need.
Internet : 20 euros/month etc.
190 euros going out etc
Tight but possible
If you are lucky you could find a small studio flat for 400 euros.
Finding a place in a safe area isn't difficult and even pretty central for that money.
