Has anyone tried private swimming lessons?

I'm a beginner swimmer..

Since I can't swim, there are too many limitations to the leisure activities I can do, so I really want to learn.

I just can't keep up doing it in a group.

So I'm thinking of taking private lessons.

Excluding swimming equipment for one session

I think the lesson fee is around 50,000 to 60,000 won...

How is it???

If I take private lessons, will my breathing improve and will I be able to swim freestyle well?

I'm totally uncoordinated when it comes to exercise, so I wonder how many times and for how many months I'll have to practice before I can swim...
