I think this is a good link for you:
You can compare different scenarios by putting different times. No bus (the metropolitan transportation system) will take you directly to the hostel, so you must walk or you must take at least two vehicles (at that time its the most likely option).
Another option would be Finnair bus, which are more expensive. On the other hand, those busses will bring you quite near to the hostel. The timetable of those busses is shown on the Finnair website.
