Love them or hate them? I personally prefer carpets because they are more cosy, particularly in winter.
When I attended ante-natal classes, this topic came up and people had strong views on it. Basically, people were fed up of the noise from their neighbours with wooden floors. It was particularly worse for those whose neighbours had children because they were subjected to constant thuds.
With wooden floors becoming more popular, I can imagine that the noise issue will become more prevalent for people living in adjoining accommodation.
There are also stories in the news of people breaking bones because they have slipped on highly polished wooden floors. Are they really that hazardous? How easy are they to keep clean?
Personally, I'll stick with my carpets .
