In that sense, I guess a 100cm2 apartment is "pretty spacious" compared to a 25cm2 one. My point was that a family of four living in a 100m2 apartment is going to feel cramped.
But it really depends on expectations. When people who live in the city visit us, they say "woah, that's a big apartment". When people who live on the countryside visit us, they say "how can you live in this tiny space".
My comment really was about how talking about "area per person" is not a good metric, because how spacious an apartment feels does not scale linearly with household size.
