Show me your local flat renting market and few things you like/dislike about it

Hey there, first time posting so hello! :)

I'm doing research on how to make renting more pleasent for customers, one of the reasons is that I currently really dislike how it is done in my local market (Poland), and how anti-customer friendly the UX of solutions is.

One of the examples that I dislike:

https://www.otodom.pl/pl/oferta/sadyba-2-pokoje-ul-limanowskiego-5-40m2-ID4anAL.html#527cd91195
You can see price in the top right corner as 1800 zł, that price is used in listings as well
But there is additional price which is added on top of that "Czynsz - dodatkowo" which is additional 400 zł
Overall it is 2200 zł, but I cannot know it before clicking the offer, and also when looking through listings some offers use that additional price and some don't, comparison is non-existent, 2000 zł flat can be cheaper than 1800 zł flat when going through the listing
Otodom is the biggest entity in online flat renting / selling in Poland :)

I'd like to learn more from foreign markets, one of the sites that I really liked was domain.com.au, especially its "Insight" section:

https://www.domain.com.au/project/3262/the-grounds-of-kew-kew-vic/
While it is not informative as I'd hope it would be, that is still so much more information than what is available in my market
Design of the site is really great compared to others that I know

For anyone that would like to know about Polish renting market (like someone doing it for other markets :) ), there are:
