Levallois-Perret is a commune bordering on central Paris, and a comparable size to a single arrondissement (subdivision within Paris proper). For example, the 11th arrondissement [1] is 50% larger and 100% denser than Levallois-Perret. But it doesn't count because it isn't it's own separate administrative area.
All this to say: the closer you look, the harder it is to rank places by population density. The comment point was that high population density can be reaching without high rises.
