Searching for local ads in foreign countries

I would like this post to be a collection of websites with local real estate and rental offers in different countries. Personally, I want to find out what the rental prices for apartments are in different countries. I am looking for websites where you can find local offers (not international real estate agencies). Please provide websites for countries where you live or which you know. For #Poland I know two websites with apartment offers: - Only houses and apartments otodom.pl https://www.otodom.pl/ - thousands of ads from different categories + many apartments olx.pl https://www.olx.pl/ Which websites offer similar listings in other countries?
