Don't know if this helps but......
Don't know what you are like for extra money, or if you have all of your time ear-marked for staying in London, but if you can get a cheap train ticket to Edinburgh, Scotland there are a couple of good places there for ladies.
The spas there are like our massage parlours except better! I was undecided as to if I should go to the London Street Sauna or Scorpio's as I have read good things about both of them (see the above link for punternet), but I found London Street Sauna first so in I went.
A good selection of ladies working. All in their 20's and all good looking, but in their own unique ways, so as to appeal to many different tastes. You pay at the door for the "massage" time, and then you go to the locker room where you put your clothes in a locker (with a bag for you to carry your valuables), and then you can take as much time as you like to have a shower, a sauna, and sit in the main room and watch TV or chat with one of the ladies as you enjoy a drink. I didn't feel that there was any pressure to hurry up and choose a lady for the massage, and was actually encouraged to relax with my drink until I had seen all of the ladies working before making my choice.
When I finally chose the lady I wanted (a gorgeous brunette whose name I can't quite remember (Brando?)
although I would if I saw her!) we headed downstairs to the comfortable private room. Had a big (real) bed, lots of mirrors, and a TV showing porno that I quickly turned off as it was featuring a vid with a hairy guy yelling in a language that I didn't understand (and was starting to ruin the fantasy). The lady was unrushed, damn sexy (I love the accent) and had as full of a menu as I thought to ask for.
In general, I think the "saunas" over there have the MP's over here beat hands-down! The atmosphere was much more friendly, and the staff seemed to have a genuine interest that I enjoy my time there. There wasn't any of the "get into the room for a quick rub-and-tug and back out again so the lady can get back to whatever she was doing" type of vibe that I have had more than a few times (although not always) here in Alberta. And the place was just generally set up differently, with the open room for guys to relax and hang out with the ladies in while making a decision for which one to spend "massage" time with, the free drinks, the real sauna to enjoy, and the locker room. The same sort of place might not fly too well over here though. At least with respect to the fact that I don't think most guys go to MP's here so that they can sit in the sauna, then hang out and have a drink and a chat while watching some football.
As I was chatting with the lady I had chosen, she asked me what the equivalent type of place in Calgary would be like. She was shocked at how basic the set-up is at most of the MP's here compared to there, and how much money guys are willing to pay here for the same services. I assured her that if she were to come to Calgary she would do quite well with her attitude and service.
Hope this helps renewal, but if you aren't going out of London, then I guess it won't. Just had to finally give a review of the London Street Sauna. It was as good as I had read about; next time I will try Scorpio's!
