I’ve been to London several times and had mixed success with pooning. I wish I had better specific advice but I’ll try.
First off, you’re correct public transport is excellent, only insane people would want a car. Where to stay will really depend on what else you’re there to see and do.
You will find many girls who use Tryst in the UK, and Adult Work is great for Indy escorts and fantastic for real reviews and what they call “field reports” but it takes time to navigate. Sign up and get a free account to get all the benefits. The first time I went to London I found a cute escort using it and had a great time, but that was before the idea of deposits existed. Now that makes it tricky.
There are lots of agencies in London, with incalls all over the city. Pop on a UK vpn and google will show you plenty of agencies. Agency websites like Babylon let you sort by location and give you a pretty accurate location when you’re searching. I’m not sure if you can use Adult Work to find reviews of agency girls, but if you can find them that would be fantastic. And let me know if you do.
2 cautions.
First we are spoiled here in Canada with both variety of girls and price. I thought there would be a better escort scene than there seems to be. most Agency girls used to be eastern European, now Brazilian tends to be popular. AdultWork and Tryst indy’s tend to be more varied. High end girls in London are very high end. If you think Vancouver and Toronto have lots of whales with deep pockets wait until you get to London and the old money, oligarchs, international finance bros and rich kids. There may be a whole other world that the locals know about, but I’m in the dark I’m afraid.
Second watch out for “Party girls” I was shocked at how many escorts advertise this. The last thing I want is a girl who’s high, so I avoid them, but it’s obviously up to you.
