I think it's hideous and I wouldn't want to live there. There's nothing "wrong" (nor "right") about the idea that lots of bold colors will tend to clash and be unpleasant. It's just subjective and different people hold different opinions about it.

This is really no different from "beautful colorful houses in the Nordics" someone gushed about in another comment.

You need consistency and care. If you have that, suddenly you are a "tourist destination", "cozy place to live" etc.

Bold colors don’t clash. Clashing colors clash. You can dislike bright colors all you want but you can’t change color theory.
