Get on Autobahn A5. Exit Ladenburg/Schriesheim is the second exit north of A5 Neckar bridge.
Use exit Ladenburg/Schriesheim from A5, then into direction of Ladenburg/Mannheim, NOT Schriesheim.
At first traffic lights, turn left to Ladenburg (Weinheimer Strasse).
At the next possibility, turn left into Hirschberger Allee.
Go straight on, do NOT turn left into Stahlbühlring yet.
After about 300m, turn left into Stahlbühlring (this is the SECOND possibility to turn left into Stahlbühlring)
After about 100m, turn left into "Im Oberen Rech", find a parking lot.
You can find our house in a small path on the right side (Look for signpost that reads: "Im Oberen Rech 20-4").
