I have visited.
There were a few things sadly lacking.
When I entered with a girl from outside, the receptionist didn't even acknowledge me, I think a pleasant welcome would be a good idea, she was busy doing something more interesting. The girl escorted me to the curtained area and there seemed to be some confusion where to go..... it was hot in there and I wanted the ceiling fan turning on as this would divert some AC my way.... either I was not understood or the girl didn't know how to turn it on.
A clothes hanger and a hook plus a small table or shelf would be useful, there was nothing, Nowhere to put clothes and belongings.
The top of the light box had an inch of dust on it.
Massage went ok although the girl was a bit limited on any extras.
It isn't really private enough, perhaps some big clips to close the curtains better are needed.
I wanted a shower, the first room I was shown nothing was in a working condition. I asked why I was put there and she said not her problem.
The shower worked in another bathroom but it needs refurbishing a bit.
Perhaps you could consider whether the girl should help with the shower, or at least offer... rather than just put you in a bathroom where the water didn't work.
There was an unpleasant smell which appeared to come from a rice cooker filled with small towels.
A little perfume needed?
It is up to you to see where most of your business comes from, but with the nice front outside area and big window with sea view I think it would be a great place for the foot/back/neck type massages for the tourists.
