This roughly means 625 €. I would classify that as far too expensive for Poland's working class. (Not even talking about minimum wage there!)
The apartment isn't meant for a cashier.
Which roughly means 237 €. Sounds reasonable, if you take into consideration the Euro is about 4 times stronger. Correct me if I'm wrong, but don't you think this should be the average in Poland? I mean 2500 PLN a month? Even a Dutch person would call that pretty expensive for a flat!
Sure, that's incredibly reasonably for an apartment half the size, unfurnished, not in the center of Wroclaw.
Reasonable is whatever the market will bear. If it's unaffordable, the apartment will sit empty until the prices go down. There are plenty of unfurnished holes in Krzyki that you can get for 1200 a month with everything paid.
Don't quite understand what the problem is. There are options. The apartment that was referenced here was 2500 a month, furnished, all bills paid, in the center, with no commission. Is it a bit high? Sure. Is it excessive for what was offered? I don't think so. Would it be excessive for a student, or a part time English teacher, or a cashier at Tesco? Probably. Would it be excessive for an engineer, a manager, a doctor, a lawyer, a pilot (we're hiring!), hell, a full time English teacher?
