Well, my apartment is heated, but it's 33 degrees outside here.
I have a blow heater blowing!
Well, I guess one of those sexy skirts for outdoors is out for you unless you want to have thermal underwear exposed!
Be very grateful that your utilities are part of your rent. If I had 33 degree days here in CA, my bill a month would be probably $850 a month higher to maintain 68 degrees.
Most (non-new) homes have little or no insulation in the walls due to the warm climate here.
