Visited 55么么哒 yesterday. As some other bros have mentioned, if you're looking for SYT, she won't tick that box. Looks wise quite similar to the photo she posted on SLG, but maybe discount 10%.
Hygiene and service standard is 10/10. Massage was strong and the sensual was good. My first time visiting and she was patient with me. Definitely a RTM for me, which is why I share this review!
