I have seen 5 girls since I am in London. Two from adultwork and three from agencies. None of them were reviewed here. I had much more greater success with random agencies girls (3 positive) than with random adultwork girls (1 negative 1 neutral). Agency girls were almost twice as expensive though.
I'll start with my best experience: Abigal from various agencies including
External Link/Members OnlyThe booking process was uneventful.
You will recognize the girl on the pictures upon meeting her. Some imperfections were removed, but nothing major. If the girl on the website is around 9.5 face wise then the real girl is around 8.5. However, I feel necessary to mention that I found her charming, so I cannot guarantee my objectivity. As for her body, you can rely on the website pictures for her ass/breasts which are amazing. She is not as perfectly lean as the pictures show, but she is still very slim. She is around mid twenty, maybe a bit older.
Service/attitude wise she is very natural and engaging. She has initiative and got me more aroused than any other girls I have met in London. This was the highlight of the punt even more so than her good looks. She did OWO/DFK, no anal as she said she needs to be told before the meeting. She claims she enjoys anal though. I could have CIM but I didn't. Sex was great, multiple positions and she was "into it": probably some faking but it was a good enough performance

.
I had a good conversation with her afterwards, she seemed well-educated and this is something that was missing in my other punts in London, especially the two romanians of adultwork. Her english is better than mine

(I'm french)
Round 2 was just as great.
Overall great punt with a charming girl, the only punt I would repeat in London.
Maybe I should mention how I proceeded to select unreviewed girls from agencies and adultwork, since I mention that I had more success with agencies.
1. Pictures had to arouse me (obviously...)
2. Perfect reviews 10/10 (or positive feedbacks for adultwork) from all reviewers
I suspect the reason I had more success with agencies is because I filtered much better with the all-10/10-criterion than with all-positive-feedback criterion, and I also payed more for the agencies girls.
