I lived at my Uncle's house for a few months when I got back to England and his entire house is laminate, even the stairs.
The house creeks like mad, you can move without making a noise.
I always wanted laminate in my room but if you are upstairs just remember the disadvantages: An office chair with wheels may scratch the laminate, not to mention make everyone downstairs think the ceiling is coming down. It is slippy so socks are a no-no when it has been cleaned... I speak from personal experience of running for the phone and ending up on my arse. Laminate attracts dust, hair, etc so it needs to be cleaned regularly.
My Uncle has 3 cats so the laminate looked like a sea of cat hair even after a few hours after cleaning it. They are going to put carpet back down everywhere now.
Laminate looks a lot better, but carpet is more practical for a bedroom.
