Accommodation options

You can look for hotels on services like booking.com or hotels.com, and most locations in downtown Helsinki have good public transportation connections to the Kumpulas campus. However, below is a list of some recommendations, where you can also check the route maps from the hotels to the meeting locations.
Well-known hotel chains in Finland:

Downtown:
