Similar issue here, my upstairs daughter is so hyperactive even on her on only. Jumping, running, throwing stuffs around always! Even during late night!

Complained to MO, MO called to the owner to give a warning, in return, owner asked me to move to landed or bungalow if cannot accept all these kind of noises. Speechless! Why they can be so inconsiderating?? Not to mention that diy guy suka suka knock n drill here and there. Sigh..

Really feels like moving out to another place
