I have no experience of this place, but it looks to be on the expensive side judging from their ad. I guess you are paying for location - meh. Don't be too surprised if HJ costs you extra, as that is entirely possible.
Why not pop over to TST, plenty of options there for good value
Oh and the milk bath - if she puts those dried rose petals in the bath for 'romance' then when you stand up to get out, fully expect to have soggy remnants of flowers glued to all over your body - I hope you are not a hairy like me - I had to be seriously hosed down to get rid of them. Overall, it's just sitting in a bath. I personally do not recommend, but each to their own.
