OLOhuone (or Olkkari) is Athene’s guild room on the 1st floor of the CS-building in Otaniemi. It’s the room with the glass wall corner, that you see when you step into the CS-building from the main entrance. OLOhuone is a place where guild members can hang out or do work. It includes a few computers, a small kitchen and sofa area.
