You will need to switch off infinite jumps in order for the achievement to work. It was a bit fiddly and I needed to exit to the main menu after turning off infinite jumps but I'm not sure if it's necessary to exit and re-enter.
when falling down, try not to touch the movement controls as this may interrupt your fall and therefore fail the attempt,

This location worked for me a few times(more often than not). I was playing on my own just using both hands on my keyboard.
