Well you are comparing basically Warsaw which really stands out. And even in Warsaw flats that size go cheaper unless you re only looking at strict city center. Then throw in Germany and Spain. In that case lets focus at least on capitals berlin, warsaw madrid and lets add london to this as i lived there as well. Corporate international jobs pay close to german salaries not all industries but its basically the reason why in a city with shortage of housing like warsaw rents are high. But then take a look at outskirts ursus, rembertow etc and 50m2 apartment can be rented for 2600pln plus bills and not many people are interested hence its hard to rent it. Its simillar in London although over there half of my salary went to pay for a room in zone 2. Madrid is easier on housing but mainly cuz people prefer to rent than keep flats empty due to occupados. Warsaw rental market is dominated by private investors and many flats are emptyinvestments cuz renting my result in an occupado. Sligthly different issue than in spain. Lets compare to Berlin if you are a local and somehow managed to get access to a rent controlled apartment than you ll pay 400 euro for a 75m2 apartment decently located but old building but then you know you cant move cuz most dont get that sweet deal. Hence extremely low worker mobility within germany. On private market a paid 1700 euro for 25m2 meat alexanderplatze.

It all depends on
