I booked a WG recently who gave me the post code to here.
As I had punted in a couple of these apartments before, thought nothing of it. However, when I phoned her from outside one of the apartments, she beckoned me in from what I thought would be something similar to the modern living quarters.
As she led me up the 'alleyway', up the flight of stairs and then into a 'room' with a shower cubicle in the corner, I started to wonder what the hell this is.
The punt itself was good and she had genuine pics. One of the reasons why I stayed was because it was getting late and couldn't be bothered trawling AW again.
It seems like either girls are turning every bit of space in to 'rooms' for clients or, more likely, the landlords knowing what goes on, are creating these.
I can only describe it as a sheltered fire escape route with a room at the top.
