The argument for the night train is usually made badly. People talk about romance, and romance is not a thing you can put in a spreadsheet next to a seventy-euro fare. Here is the version that survives arithmetic.
A sleeper from Vienna leaves at about nine and puts you in Venice a little after eight. That is thirteen hours of a journey you were going to spend somewhere anyway, and it replaces a night of accommodation. Against a flight you are trading two hours in the air for zero hours at two airports, zero transfers, and one fewer hotel night.

What it actually costs
- Couchette, six berth: the cheap option, and fine if you are on your own and sleep through anything.
- Couchette, four berth: the sweet spot. Enough room to sit up, cheap enough to still beat a hotel.
- Sleeper with a basin: roughly double, and worth it exactly once, on the night before something that matters.
The sleeper is not a way to see a country. It is a way to be somewhere else in the morning without having spent a day getting there.
When not to
Do not take it if the train arrives before seven, because nothing is open and you will spend two hours in a station with a bag. Do not take it two nights running. And do not take it expecting silence: a sleeper is a corridor of doors, and at four in the morning somebody always needs the one at the end.
