Find the front door by using the adress: Neutronstraat 7 - 20.
Scan the QR-code with the Sportivity app to open the door.
Climb up three staircases and walk a little further till you see the entrance to the right.
Note: you can only enter the building once you've signed up for a class. The website will guide you to Sportivity and with their app you can enter. If you would like to enter without attending a class, you can ring the doorbell by pressing 1 on the machine to the right of the front door and then the little bell sign.
