Replying to
@seatsixtyone@mas.to last August I used your awesome website to plan a trip to Carcassone. I caught the Eurostar to Paris, I'd prebought my metro tickets on the very simple phone app, got myself to Austerlitz and jumped on the sleeper train. It was awesome. It wasn't the best night's sleep I'd ever had, but Tbh I arrived in Carcassonne much more relaxed that when I've travelled before by air.
Sleeper train is definitely something I'll do again.
