A small 2-lady place with good service.
I lived in Suzhou for 5+ years but moved back to the USA. Still get to Shanghai for work but not Suzhou and have been frustrated with the level of service and prices in Shanghai. Luckily one of the ladies I saw regularly in Suzhou moved with another lady to Shanghai and they do massage out of their apartment. I was a little worried the first time because it is a very Chinese sort of apartment and area, but it turned out well. Seems not having a direct Mama-san leaves them both giving better service than when in Suzhou. Anyway, PM me and I'll send you the WeChat info and a photo or two. The massage is 60 minutes with he included for no tip. I think more is on the table if you want to tip too, but certainly just for he it is a pretty good service. They go the extra mile to tease and build you up, much better than a lot of places I have been to.
The one who does the talking on WeChat is called Yang Yang and you have to translate on WeChat to communicate, she doesn't speak any English. She sends you the location on WeChat and from there it is easy. The work out of XuHui District near CaoHeJing Street and Nanning Road on the south west side sorta by the south train station.
