Edit: Looking at some stats here [1] and it looks like 565 euros is enough to rent an apartment outside of city center. It also looks like one could potentially find something for 450 which leaves pretty decent money for food and perhaps a bicycle for transportation? Definitely not enough if you consider utilities though. That's some rough living.
