In Vienna, I’m unable to install an air conditioner that hangs out of my window, so I’m forced to endure unbearable temperatures of 30 degrees Celsius in my apartment during the summer months.

Every unit in the apartment building my Airbnb is in has an air conditioner outside. And no-one is stopping you from fixing it by crawling on top of it 10 floors above the ground!
You must live in an old building. My understanding is that you can't put the external unit on the facade. I live in a new building and we have floor cooling. I didn't expect it to be enough, but it's amazing.
Floor cooling systems provide only a limited temperature range adjustment, typically a few degrees, compared to a standard wall-mounted air conditioner.
Vienna is an old city, with many buildings dating back centuries. However, this should not be used as an excuse. AC should come as standard like in the US.
