I'm in London soon and wouldn't mind trying a walk up, but I've just been looking at a few of the addresses given on this thread on Streetview and I can't see shit. How the fuck do you know where to go? Knowing my luck I'll end up in some posh restaurant or accountant's office. Is it a case of looking at some tiny little sign on the door next to the flat buzzers? In which case you have to keep walking from door to door looking at the buzzers to find where the girls are? Hardly the most discreet. Anyone got a link to an address you can clearly see on streetview so I can see what I'm looking for?
The front door of the walk ups are always open and sometimes they have notices saying "Model" on some of them. Have a look at this picture. This is Peter Street, Nos 28 and 27
As far as I know No. 27 was raided and closed in December last year. No. 28 is still open, so check the wiki (on the OP this thread) to see which girl is working on what day.
This next one is 70a Berwick Street (the open door just behind that girl) between Acess. World and Jewellers.
You can't really miss the walk ups, they are very obvious.
Good luck and let us know how you get on
