Just an advance warning that this was a b&s - I'm giving a bit of leeway for confusion here, though having just seen the othger review this may be a poor assumption.

External Link/Members OnlyComms: Reasonable, phone a few hours prior to the appointment to get a time, confirmed one hour in advanced. Nearer the time (and having got into the area) texted to get an address and was asked if I could wait a few minutes. About 10 minutes past and I got the address, and made my way to it.
Venue: House in residential area near station, door in the manner of terraced houses is next to neighbours door, but was able to get to it and ring the bell without bumping into anyone. Place was reasonably clean inside if a bit bare as is the manner of such things.
Met by a girl in dark hair who took me up to the room - when I got up there I asked for Megan and she seemed not to notice and asked me how long I wanted to stay for. I stated that I'd booked Megan over the phone for an hour - she held up her hand and went outside - presumably to talk to someone - returned and said Megan was still with a previous customer and would be half an hour but I could see her instead if I wanted. Made my excuses and headed out - she took it in good grace and I didn't experience any hassle on the way out.
So it's possible her previous booking overran - but having seen the other review, it sounds like they are either disorganized or double booking on purpose - can't see the girl with the dark hair on AW, and she definitely wasn't the girl in the photos posted on that thread.
