Carmens is OK. Nothing special.
They're beauticians are quite friendly and the prices are decent, HOWEVER don't expect to relax here. You'll spend the whole saying, "No thanks" to all these 'casually' suggested extras.
I went in there to get a facial with eyebrow wax, and an eyelash tint (which they managed to get all underneath my eyes). During the facial I was suggested the following would 'look great' on me: eyebrow tint, lip wax, upgraded facial, eyelash perm, paraffin wax treatment on face, paraffin wax treatment on hands, purchasing a gel, purchasing a mask. It was a bit much when all I wanted was to relax and was already spending quite enough there.
I ended up getting an eyebrow wax added to my treatment as I had been considering it previously and they did a TERRIBLE job. First and last time I'll ever get it done. I currently have dark blonde hair and dark brown lashes. Not a good look.
Not to mention there was a member of staff in the room next to me swearing loudly on her phone about a fine.
All in all, OK prices, nice enough women with way too much push for business that ruins the entire experience.
