Rental house heating issues

I'm new to the area and have had a terrible time keeping my rental house heated. It's baseboard heating which I realize is less than ideal but on the coldest days I can't get the temperature in those rooms over 57 degrees sometimes. And my electric bill is over $700 this month which seems outrageous considering I can't even get the house warm. It is an older house, built in 1920 I think.

Is this normal here?
