There are quite a number of reviews of this place on UKP but it's difficult to index as it doesn't have an easy reference like, for example, an AW number. I imagine it would be quite a long manual job for admin to merge all the reviews together somehow.
I've visited a number of times and generally had a good experience. I'm quite fussy and it's important to me that the girl speaks good English. What I've learned is that it's best to insist on seeing a girl you like, rather than being palmed off with some fat old munter. Otherwise be prepared to walk and leave it for another day.
The "house style" seems to be a vigorous massage which is very good. I've also had a gentle exciting massage well done too. If you just want HR as an extra, I've always paid £20.
