Yeh, think you should take the late bit lightly.
Personally not my type and probably should have requested those photos before making a booking with her, which I unfortunately did not as looks-wise not my type at all.
She was on time when she came to my hotel and provided good GFE and very friendly, although even so she did leave 15 minutes or so early... so
But other than that - nothing wrong with services just an advice would be to ask for pics (especially if you have certain preferences for looks)
Personally - not good enough for me to re-book her when Im down in London the coming month.
