How do I fix a hole in my bedroom floor?

No problems with the floor infrastructure...you don't say how this occurred but the floor boards are laid on top of timber joists and normally you'd cut the damaged board away with a jigsaw before fixing in a new panel. However, if the hole is round, why not plug it with some dowel which you've sanded to a slight taper, add some glue and hammer it in? When dry you can cut the excess off and then plane it down to floor level.
