The main station is Glavni Kolodvor. I arrived sometime around 21:00-22:00 at night to the train station, so I’m not sure if the station doors are open 24 hours. But if you are there early enough, you’re allowed to sleep at the station (they won’t kick you out). The stores in the station are closed during this time though.
The station is across from the King Tomislav statue.
WHERE YOU CAN SLEEP:
I know for sure that you can sleep
- In the hallway where the lockers are
- On the metal chairs on the platform
Enjoy this interesting and creative wall painting that I found when I was walking to the train station
