I'm glad to be of help. And I know what you mean about addreses. I tried locating the sauna by following the house numbers at first. And that didn't turn out too well because the numbers ran up and down in not-necesssarily sequential ordering on both sides of the road named in the published address. It was only after asking a very helpful ladyboy that I finally found the place.
I can't say that my time was wasted though, because I also found Hatyai's small collection of gay boy bars (and girly bars), while wandering around.
