If someone did that in one of my places without asking their bond money would be going towards replacing those floorboards. Much easier to bolt it to wall studs, then all you have is a little gyprock patching & painting when you remove it. It won't move if you get it bolted top & bottom to the studs.
This, decent 8mm or so Teks into the wall studs top and bottom and it will be very hard to move, in many cases superior to a loxon in concrete as the safe itself cannot be used as a lever to pull out the loxon or whatever masonry anchor you use. A bit of filler and paint when you leave and you get your bond back, Cheers.
