We have two bedrooms in our newly finished loft conversion. I have always dreamed of wood flooring but have heard that it's a) noisy for downstairs rooms and b) more expensive than a mid range carpet due to fitting costs. We have two very active toddlers. Would you carpet loft bedrooms? If so, would you use wool / polypropylene or a mix? I have heard that grey carpets are the 'new beige' - I prefer beige but don't want it to date too quickly. Advice please!
