I can't help but feel most people here are moaning/critiquing things that come down to personal taste. The windows not lining up is annoying and I appreciate people's issue with the smell sometimes, but the interior spec, announcements, seat comfort etc is all down to personal taste. I find them cosy, but I travel on them sporadically and when I'm planning a nice journey so I can pick first advances or cherry pick quiet services etc but I can see them being uncomfortable when cramped, but hey, which train isn't.
