If you find the brothel in Verdistis, complete another quest involving an assassin who has a room there (screenshot), and ask the bartender about 'special treatment', you can engage her services (which are somewhat more specialized than the full time employees). After the screen fades to black and comes back, you are in the main brothel room with a few more experience points and only 1 hit point left (presumably at least in part due to the spiky bed).
