I'm still not convinced that south facing is the way to go. Oppressively hot for three months of the year. As I said before, my north facing balcony is far more comfortable, although I am fortunate in that I'm on the end of a block and therefore, in the winter, get morning sun right until lunchtime on the side of the apartment to warm it up. The other bonus is that I also get a decent view from my balcony.
