Mine is set at 62 during the day, 60 at night. I have only one thermostat for my entire apartment and it is in the coldest room (floor to ceiling windows on two sides of the room); the temperature in my living room tends to remain between 66 and 68 degrees.

I keep a humidifier running all the time once the temperature drops. I feel that helps with the temperature (and my skin and wooden furniture also enjoy the humidity).

A ceiling fan also helps with better air distribution. When at home, I tend wear socks and a light fleece pullover.
