swimming pool search and the alexander teachnique

Hi,
I would like to improve my swimming and have been looking around for a nice pool.  I've seen a few like the Balthus, Spa Providencia, the 02 Club, Planet Fitness and some other ones that were too basic.  The above seem to be either too expensive (Balthus) or too small.  Spa providencia seems alright but still not quite what I'm looking for.  If anyone knows of others in Vitacura or Las condes area, do let me know please. 

I'm also wondering if anyone knows someone who teaches the ALEXANDER technique in swimming, I've been researching on the internet but could only find them teaching in Argentina.

Grateful for any leads.
