Den Haag (The Hague, 's Gravenhage) has two red light districts. The most well known lies on the streets of Geleenstraat and Hunsestraat around 500m NE of the Den Haag HS station. Around 700m NW of the station is the second on Doubletstraat. There used to be a third very small district on Poeldijkstraat but this was closed down around 1999 due to crime and general nuisance.
Below are photos of Geleenstraat and Hunsestraat.

The area around Geleenstraat and Hunsestraat is much less touristy than the main red light district in Amsterdam. It has none of the adult shops or shows.
I took these photos in January 2011 around 10am.
A kamer / window map of the area can be found here.
The map above shows the location of the two red light districts as well as a few nearby hotels. Using the search function or clicking on the blue logo will give a lot more in the surrounding areas.
Below are photos of the second red light district situated on Doubletstraat. I can only describe the area as down market compared with Geleenstraat and Hunsestraat. I can't imagine many tourists going here and assume it's mainly used by the locals. Although very compact it has a large number of windows / kamers. A map of which can be see here (sorry, link is sometimes down, it's not mine).
I regret that I was unable to get enough photos to construct an interactive map of either area. Perhaps one day I will manage it.
