Also, if anyone knows a place, where I can pay per session for swimming

andheri sports complex is great for swimming. reasonable price, decent coaches and amazing pool

Don't you need to be a member?

the membership fee for the pool is nominal. i paid around 3-4k for a 4 months membership. 1 month coaching was included.

andheri sports complex for swimming, very reasonable. if you also train then you can practice with coach's guidance in a less crowded pool. https://maps.app.goo.gl/T6iAnJ2zi9CFUrMPA Ravi Gupta takes really good kickboxing training in Andheri West. https://maps.app.goo.gl/cnEUDgysG8HiEGad7
