So with the laws the way they are in Paris there is impossible to find someone local with the same level of service and reliability as Montreal. In fact when I checked information on local women most of the reviews I saw indicated bait and switch and poor service. I used a Russian agency, and it was a pleasant experience (I would say not bad by Montreal standards). It was a long booking so I got to know her both in my room and out at dinner. She worked in HR at some office St. Petersberg and had said that she would have gone to London but its much more difficult to get a visa there. I offered to extend but she declined at said that it was Friday night and she wanted to go clubbing, and so we parted ways. I never got the impression that she was being coerced or that anything improper was going on. Sad to hear now that this might not be the case.
I only flew my own entertainment into Paris after that, but the agency I used and Amour Russe were well reviewed so I am sorry to hear this. Will have to google translate that article.
