And when it runs of course I’d favour the Berlin-Hamburg-Malmö-Stockholm #CrossBorderRail night train here. But Finnlines Travemünde-Malmö is a great ferry route
It’s a huge but basic ferry, mostly truckers on board, and it’s so calm. I slept very soundly. No partying on board. Only a tiny duty free shop. I really like it - and generally I don’t like ferries.
