I'm in a smallish one bedroom apartment. I have both heat and AC. During the summer I try for 75 to 80 during the day and 65 to 70 at night. During the winter about 5 degrees cooler. My bedroom is a few degrees cooler than the living room and also, therefore, a bit more humid.
Both have floor to ceiling walls of windows which face east, so I get a lot of ambient light during the first half of the day. Which I supplement with lights.
