Besides being beginner friendly (forgiving mistakes), easy to learn and see the progress quickly (instant gratification, quick catch-up with friends who started earlier) the fact that it's not as physically exhausting as squash or tennis makes it attractive for many people.

I see a lot of people transition from squash and tennis to padel nowadays and basically any racket sport experience helps it a lot.
