Different things you can make the floor look nice
I use Bona on my floors. Bed, Bath and Beyond carries it. It makes the floor look brand new!
Have you given any thought to using stencils and paint. I have seen some beautiful results here on Home Talk. You can completely change the look of the entire room with a new floor. There are literally thousands of patterns to choose from. If you have never used stencils, I recommend practicing on cardboard first. Good luck.
