Small in comparison with a typical single family homes that goes >150 sqm in my area. I completely agree with you, 99 sqm is more than enough for a 4 people family.
it depends on how you can use the space. 4 people can mean three bedrooms. in some parts of asia the average 3-bedroom flat is 150m². a few years ago i did a search in a european city and likewise was unable to find 3-bedroom apartments with less than 120m². 4 was 150m² minimum.
the problem is huge living rooms that can't be divided up and repurposed to make living space for more people.
work from home doesn't need a lot of space, but with young kids i absolutely need a lockable room. my current office room is 5m². plenty of space. but finding an apartment with that kind of room is rare.

You simply chose the wrong European city :) Try Dublin, the city of 70sqm 3 bed apartments (in fairness, these aren't allowed under current planning regs, but there are quite a lot of old ones).
