The latitude of the northernmost point in Antarctica (63°S) is comparable to substantial settlements in the northern hemisphere such as Anchorage (61°N) or Fairbanks (64°N), but the conditions for habitation appear to be much worse. What is the reason for this?

Definitely geography.

The polar front (air currents) effectively isolate Antarctica from outside climate influences. However, the ocean moderates the temperatures near the coast; this is why Fairbanks gets colder and has wilder temperature swings than the Antarctic Peninsula.
