Does this sound like adequate heat for 750 sq ft bottom level apartment in a home?

6. We Once Rented An Older Home

Window, unless they are modern replacements, leak badly. Maybe the landlord will pop for 3M window kits.
Second, our fireplace had a terribly leaky damper. I placed a card table in front of the hearth & it made a huge difference.
Finally, in our house now, we have a basement rec room. Since the house is heated with circulating hot water, you need the fin & tube radiators, which the basement doesn't have. The basement has to direct walkout to the backyard ao that wall is exposed to the elements. To take the chill out, we have a quartz block heater. We upgraded to one that looks like a small fireplace, but still have the old one.
It works really well. Safer than electric resistance coils because the surface doesn't get hot enough to start paper or fabric on fire. Nearly 100% efficient, too.
