I went there for the first time in the past week.
There are other companies in the building which you will need to walk past so it is not the most discrete. The women working there were not what you would call young, I would say late 30's to early 40's and the one that I could didn't seem to speak much English. The massage was probably to the standards you would expect from these places.
There wasn't much teasing and only HR was offered. I paid £40 for an hour and HR was £10.
