Not central Europe. I'm in Croatia and everyone I know has it. I have it in every room (split units), and have had it in every rented apartment since I stopped renting student accommodation.
I'm not saying it's prevalent everywhere in Europe, I'm saying that it's a bad generalisation because it varies a lot within Europe.
Note that while you point out this happened in specific areas you've lived in, there are unfortunately plenty of places in Europe where you'd face the same issue.
