Freiburg im Breisgau - 53 Dietenbachstraße

It's a simple car park just outside of a resential area. There is a caravan apparently parking there long-term, apart from that there is almost no cars. In the morning this is a main connection for pedestrians and bikes (also groups of school kids) and there is glas bins just next to it which are allow to be used from 8am to 6 pm. Perfect for one night. You can still hear the motorway a little bit but it's shielded by the trees.
