There was a small rent price drop during Covid in some hot property markets that were popular as being the country's cultural / tourist capital (e.g. New York or Amsterdam). When the lockdowns it's hard to sell a $200 a night hotel or a $2000 a month rent to people who can't even go to a restaurant or museum.

But even with the modest drops, rental prices in such cities are still waaaaaay above anywhere else, and the prices are already on the rise again.

Apart from that I have no clue what you're referring to.

Where in the EU? From my perspective it's consistently getting crazier and crazier in the capitals. I also see a lot of cheap rural property in Germany, Estonia, Portugal, Poland etc.
