The best place I know of is Maria Massage in Huaykwang, Bangkok. The rooms are super fancy. All the girls there are at least 7.5/10.
The lowest tiers of girl start at 6100 baht, but these girls are all stunners. When I was taking a look, I was overwhelmed by all these beautiful looking girls. I was actually getting nervous looking at all these girls
You can get a glimpse of this if you search Maria Entertainment. I think this place is definitely worth a visit if you're willing to spend the 6000 baht. This was by far the most upscale and rooms are very very nice, just like a 5 star hotel. Well worth the experience
