Used it in 2014. They had a flat in Canary Wharf (next Sainsbury's on westferry road) I have been show 2 girls, very young (maybe early 20 both) one was Singaporean petite, super pretty with nice little butt. The other one was from Hungary, blond less pretty but really nice body. I went for the Asian one who give me OWO and CIM
Price was quite high. 150 for 30mn if I remember correctly.
