Hey mate,
I didn’t punt in Düsseldorf but if RLD’s are your thing, Duisburg Hbf is only 10-15 mins away on the train.
Take the U Bahn from Hbf to Platenhof and it’s less than a 10 minute walk to Vulkanstraße.
There are loads of smoking hot girls available for €30 basic or €50+ non rushed. You’d be hard pressed to find a better selection of girls in Germany.
Check out some of Splodge’s posts - all very informative!
