Light Requirements for Growing a Gardenia Indoors

I have a little indoor gardenia which I recently bought. I have 2 locations to choose from, but am not sure which is best.
I have one room with a south window.
The second room is one with 2 windows, one to the south and the other to the west. The west window gets direct sun later in the afternoon. The 2nd room is lighter because it has 2 windows, obviously.
So which room shall I place my gardenia in? Please advise.
