I've got a Bamboo floor in the living room, about 35 sqm. ([broken link removed], the darker, carbonised version - albeit I paid much less than it is now!)
It is very hard, and ages very well (have it about 5 years now). I really do like the "grain" or pattern of the floor boards.
The boards are however very hard, so it requires a bit more effort than usual to cut them.
Thickness is 15mm so can be easily sanded down if it is necessary in years ahead.
As it is laminated wood, it doesn't expand as much which is good as you want to put it over underfloor heating. However, given the thickness and density, it proably does insulate very well indeed which might make it less ideal for underfloor heating.
All in all, great floor.
