The Procom-Haus is located directly on Hamburg's Rathausmarkt and is easy to reach by public transport: take underground lines 1, 2 and 4 or S-Bahn lines 1, 2 and 3 to Jungfernstieg, or underground line 3 to Rathaus. Numerous bus routes (including 3, 4, 5, 6 and 17) also stop directly at Rathausmarkt. If you are travelling by car, the Europapassage car park on Hermannstraße is your best option (about a 2-minute walk).
