We have it in the kitchen ... it's great although I must be honest, we find it hard to keep clean but maybe that's down to the style we chose (cream) ... the dirt seems to get ingrained. Gave it the annual strip at Christmas and it looks lots better. I do like it though and would have it again.
I have karndean in my current bathroom and had amtico in my last house. If I had to chose again, I think I preferred the amtico, but they didn't do it in the pattern we wanted when we were doing up our current bathroom. I just use those disposable floor wipes on mine and have never got around to stripping and resealing and it looks fine but it is a small area.
