I too have tooted my own face off in this hotel! So rare to find somewhere with the room for a pool in amsterdam (it is tiny). They have had a big referb since I stayed there, so don't know how much has changed...
Exit the main doors and head to your left, please walk right past the little Grasshopper c/s and do go in Homegrown fantasy, a little further along.
Great location.
If you are interested in the red lights the main drag is where the pretty girls are. Always amazed me how sexy some of the girls are, not the image I had in my head of a prostitute. For an authentic experience you must check out the tiny red light alleys...
