Used them several times a couple of years ago when I first started punting as just seemed a simple way to get a girl to visit my hotel when I’d finished work in the evening.
For me, no real research required and would just call up on spur of the moment and see if any I liked the look of were available.
Obviously, the photos aren’t totally representative but they are at least of the girl you will meet; services very basic and normally consist of girl strips off, covered bj and basic sex until you pop in the dom. I received very strict instructions from one girl - no touching of her pubic area !!
I guess it serves a purpose and not sure what you should expect for a £79 outcall in London 🤔
Being a more seasoned punter now, I’d be looking at alternative options
