I'm looking for a dance studio that teaches salsa, does anyone have any recommendations? (plus side question about gyms)

I'm in town for a month and a half. I live in Pudong, but travelling to Puxi isn't a problem as I have nothing better to do. I have zero experience in any dance.

Also, does anyone have any gym guanxi willing to help me out? I'm looking for a place where I can work out for a month, but most places have at least a three month binding period.

Cheers!
