I had the exact same issue with her on Friday. I got a very quick text back to confirm 30min incall in Notts at 4:30pm. The postcode supplied to me straight to an NCP car park in Lace Market area. So I parked up and text again and within 2 mins got the location, floor and apartment details. Profile says English but got the impression English not her first language (but who knows with text speak nowadays!).
I walked to the location and there were 4 women outside sharing a cigarette with southern accents(maybe totally unrelated), so I walked past and waited till they finished and went inside the serviced apartments.
Got to the door on the street and pressed the buzzer .. no answer. Tried again but started to feel very self conscious as people were leaving work. So text again and got " Wait 5 mins, friend has client"
Decided enough was enough so back to car, paid £4.50 parking and drove off :-(
