One of the ways we have tried to make the HTWG Konstanz campus more family-friendly can be seen in the cafeteria. The campus cafeteria is accessible for baby carriages and has an elevator to get to the second floor. Speak to the cafeteria staff for access.
The cafeteria has high seats for children, and best of all, children of student parents up to 10-years of age eat for free. You just need to get a MensaKidsCard at the Seezeit student union.
