How can I make cleaning my appartment fun

Put some music on & dance like nobody is watching, lol

Start slowly. Once you rid of useless things. Have a bubble bath and good sleep

Your favorite playlist on earphones, dancing!

Put on your favourite music

If you figure this out, let me know

Time it...

Music
Time your activities
Do unnecessary squats or kicks each time you pick up something.
I've done it all and burned so many calories and lost weight due to cleaning.

Beer always worked for me.
