This place has been well-reviewed, so no need for me to go all Mills & Boon.
I've had a few visits in recent months, so this is kind of an aggregated review as they were largely identical. I texted the store owner (older Asian lady who greets on arrival) on the number listed in Google Maps, and asked about availability. I was pretty up-front that I wanted a "young and pretty" girl, and she was very keen to stress that all her girls were "young and pretty". She knows the score.
The place looks legit enough from the street that you wouldn't be embarrassed to enter, but once you're inside it's fairly obvious what the setup is. 3-4 (not sure) small massage rooms, each with its own en-suite shower. All have always been impeccably clean and tidy. I've never seen anyone else there, and the walls are thick enough that I've never heard them either.
The girls appear to work on rotation between shops across the country, and tend to be here for 2-3 weeks at a time with a few months between return visits. All the girls I've had have been Chinese, with varying levels of English commensurate with time in the UK, and all have been chatty and pleasant. I could list out names, but it would be useless if you're not able to predict when they will be there. I've had a 100% success rate here, so I don't think picking individual girls will make a difference.
£45 gets you an hour (I think £25 for 30min), and the massages in general have been decent without being amazing. They all seem to have a good work ethic, and will gladly concentrate where you ask and vary the pressure etc..
At the 30min mark the CC swipes tend to start innocently enough, but a few mins later the game is very much up. Every girl I've been with has openly asked what I wanted, and B2B is typically £50 (I've never asked for or been offered more). I'm sure it's possible to haggle to £40, but I'd prefer to pay them a tenner more given how little they probably earn. The B2B and HE have been delivered in a variety of different ways and with varying levels of enthusiasm and touching allowed, but in general I can't say I've ever had a worse than 6/10 experience.
Overall, highly recommended as a dead-cert that delivers.
