Where to go for Thai Massages (Preferably with Happy Endings)

I heard they are everywhere, however, where can I go that will provide happy endings but also where I will feel safe to leave my bag on the side and be naked while I get massaged?

I don't wanna be getting these massages in the ghetto where my belongings could be stolen, need a clean good safe spot.

Also, what are the usual rates for massages? and with happy endings?
