I was in MTY recently and booked a session with Angela from https://www.bomboncitasregias.com/girls/angela.html
An absolute knockout of a woman. The agency TCB was excellent, prompt replies through whatsapp and all the info I needed. Agreed on a time and a motel and she showed up right on time looking amazing. We had an excellent session and although you can find providers for way cheaper and you might get lucky, this agency seems to take their stuff very seriously. The pics were real (albeit obviously photoshopped) but it was 100% the girl in the pics. So if you travel to MTY and want a premium provider... check these people out:
