on the floor
There is a Church mission on the West side of the main train station, mainly for homeless people and people with problems. But it's very clean, people are friendly, and if one is humble and polite, there is a good chance you can enter to chat even in English and sleep there on the floor in your sleeping bag. The night shift opens the place at midnight and everyone has to leave before seven in the morning.
Nevertheless, as a traveller, you should contribute some money to run the volunteer's service or at the very least offer some help. Remember: This is not a place for the unprepared traveller and definitely not a hotel!
