Stemol,
If u have to stay in Gz :
Moon Bay Hotel has Jing Jie Health Club
or next to Guangzhou Htl, Jin Sa Massage
3rd floor, Guangzhou Dunhe Business Apartment (广州敦和商务公寓 / Guangzhou Dunhe Shangwu Gongyu)
No. 855 Guangzhou Avenue South (广州大道南 / Guangzhou Dadao Nan)
There're some big MP arround Train sta. arround LianHua area.
You'll see some "SAUNA/SPA" adv. light outside the building.
They say Song na for Sauna (mostly the girl will do the service)
I've tried some places in Gz, but CP - DG is better...
Tianhe is a "campus" area, nice & clean... not for a dirty man like you...
