Does bamboo look as good as timber floors?
It looks different. Bamboo tends to have a fairly uniform linear appearance, whereas there are many timbers and each has its own colouration, grain etc. If you are a lover of rich interesting woodgrain, you may find bamboo a bit boring. Its all a matter of taste.
Some bamboo products have a hi-gloss finish. You should decide whether you like that finish. Keep in mind that any hi-gloss finish will tend to highlight any surface variations.
