I've seen Amy recently, the massage is nice enough and she offers extras in the form of hand relief or oral without condom for a reasonable price (the massage was £30 for half an hour and an extra £30 for oral). The downside is that she isn't attractive, it's harsh but unfortunately true.
There is a girl called Jasmine who also works in the same place but at limited times (link below), she is younger and much more attractive with a great pair of tits! I saw her once before and I'm fairly sure she offers extras as well but would be best to ask her to confirm.
There may be others who work there too but you'll need to search gumtree for that.
