There has been some ambiguity in when the dormitories are open, so here is a clarification: Between 08:00-20:00, the dormitories are open for free access. At other times, they will open once an hour at half past one. Ex. 00:30, 01:30 etc.
Now there is a portal page with all the schedules in digital format as well as the overview map that shows where all the buildings are located and which hall numbers you find in which building. You can find it in the menu under Info / Schedules & Map Here we will continuously update if any changes occur, so it may be worth checking in for the latest version.
