Thanks for the tips guys. I tried a completely different approach
Chuchi has been super well behaved and obedient so i gave him a CHANCE!
Closed my door and gave him the rest of the apartment (150m2 to himself) and when I left I showed him where his crate was, said his trigger word and left him there. I thought it was a good idea until at 2 AM he was walking around the entire house lol, all I could hear were his footsteps. He didn't destroy anything but he has to learn when his bed time is. I took him back to his room, left the crate open and left a doggy diaper pad on the floor. That seemed to work much better
