Went here for a hen do, we went for a package that included a half hour treatment, use of the spa facilities and an afternoon tea.
I have to say whilst I had a lovely time celebrating my friends upcoming wedding I was very disappointed with the spa. The spa consisted of a pool, jaccuzi and a steam room, that was it, hardly call it a spa, more like what you get after a gym session! The treatment was lovely but the relaxation room we were taken to after was next door to the gym so we heard loud base music from an exercise class that was taking place, not very well thought out. The afternoon tea was very nice however as it takes place in the hotel we had to be full dressed and showered, rather lost the spa day feel due to this. Personally if this is the best spa that Cardiff has to offer then they are in need of some more. Save your pennies and go somewhere else.
