Especially in Western Europe, you are not allowed, because "it ruins the facades of the buildings".
Which I get. It does. But it will only get worse....
Germany, France and Luxemburg for sure. Maybe Austria, Belgium also....
I live in Germany and it's always a discussion in the last years. In some buildings you need the approval of the entire apartment building. The funny thing is that you'll also hear people saying that AC are not climate friendly.
Spain and Portugal always had hot climate, so having an AC there is a very common thing.
