Do you know what the price is per square metre Lizzy?
If you want soft under foot I would recommend you spend a little extra on the underlay too.
I used to hate carpet because it looked flat and would stain. I am now converted and would happily put carpet in most of our next house. I would keep wood in some areas like halls and dining and kitchen as it adds to resale and you don't want carpet there anyway. But a good carpet I think is more durable than wood.
Then get yourself a little robot vacuum cleaner and put your feet up
