Given that it was Zürich where CHF = PLN looking at sticker prices(with exceptions), my cost of living as a percentage of salary actually went down since I was renting a room instead of a whole apartment.

In terms of what I could nominally save every month the difference was enormous.

But yeah, with a child on board I would definitely have to get something larger paying somewhere in the order of 25-35% of my salary. But that's just CHF = PLN again, so no increase here.
