If this view does not inspire you... High above the canal in Mannheims multiculti-pop-creative district is CAFE 33 in the Haus der Popakademie with plenty of coffee, snacks, and drinks to go around. Vending machines are also there to satisfy your after-hour needs.
With the addition of the Popakademie, the Studierendenwerk Mannheim was able to add another Cafe to their list. Silvia Fahner is there daily from 9:00am-2:00pm for its guests.
Payments are made with the student card/MensA card like in the other cafeterias, cafes, washing and copy machines of the Studierendenwerk.
