tbh dk, or better, CPH is the best metropolitan city to live in in EU imo. Living costs in munich, paris, london and alike are so fucking high compared to salaries that it's a disgrace.
I lived in munich for a while and rent for 1bedroom 30sqm appartement was 900€ (50+% of avg. salary). 300k+ to buy it and I knew people who paid even more than that and were happy to do so. Salary was at 2.1k Euro net/ month and that was above average already. Most get like 1.5-1.8k after tax. Owning a place is impossible there, unless you want to live in a rathole or make 4k+ net. Only guy I know who owns a place earns 6 figures and only managed to do so cause his wife inherited an apartement that she sold.
Pizza? Anything that isn't margherita = 12+Euro. I ate outside like 3 times a year. Durum? 6,50-7€.
In cph salaries are high, while living costs are medium and people can afford to own a place, even if they have a not so good job. My gf there earned 3k€ after tax in a hotel, while I ran around with 2k€ after 10yrs experience in an overpaid sector in germany.
public transport, alcohol and eating outside in dk is expensive, but again. Compared to salaries, it's just fine. Groceries are slightly more expensive than in Germany.
I was actually about to move, but things turned out different...
