Alternatively, coming from the car park, you can walk along the building on the right until you reach the entrance “Mensa”. If you follow the corridor and then turn left, you will first reach the refectory. From there, another corridor leads to the right to a lift. The lift (alternatively via the stairs on the left) will take you to the 6th floor. If you go through this, you will reach the IRDT premises after about half of the corridor.
