Have been to all of these at least once.

Ashley's I've only been to once and had a very unenthusiastic massage which put me off from going back.

Golden Castle I've been a couple of times but don't rate it as highly as the other 2.

Massage joint next to Domino's is ok but the rooms were a bit small and the girl quality has been hit and miss. Friendly staff though and my last time there with a young Chinese girl was good

Castle Hill Massage in Terminus is my favourite, weirdly I don't feel as exposed going there as the other places because it's set back a bit, been there 3 or 4 times and the most recent times were the best yet. Last one on a Monday I got a nice B2B, pussy slide and some light tongue play, I forget her name but I've seen 3 different girls there and all been great
