I cant see the link for the Gumtree Whitechapel ad now but below review has her old link.

The punt didn't actually take place but just posting a review to highlight that she is a timewaster. Booked appointment well in advance, confirmed before starting from my place, travelled an hour, reached on time , called her only to be told that she is double booked. Got a feeling that this is not the first time she has done this, total waste of time.
