I've taken that route in a couchette car twice. I haven't had any issues and didn't find the quality of the service to be any different than other NightJets. I mean, it's not exactly luxury travel (in a couchette car), but I have nothing to complain about.
I'm not a fan of the fact that ÖBB couchette compartments don't have locks on their doors. But the sleeper cabins do. Were the people who were robbed in a sleeper?
These were all books that were quite recently published and I have seen all of them in bookshops.
In the past, I have received n>1 books which were sold by marketplace sellers but fulfilled by Amazon. Same inscription "Printed by Amazon", but these clearly had things wrong with them, like font issues.
