I prefer the look of twist pile but they seem to flatten really easily and we ave a v narrow landing so I fear that the pile will look dreadful in the middle. People keep saying to go for a loop pile with a fleck. Am all for the fleck for hiding the muck but apparently they are a nightmare to clean if muck gets into the pile? The same carpet will also be up the stairs and in 3 of the bedrooms....anyone got any advice? Thanks.
