The atmosphere does have 900 degree sulfuric acid at the surface and just above. It also has a surface pressure like being a mile underwater. Carbon dioxide is actually a fluid at that pressure, not a gas.
However at the altitude where the atmospheric pressure is like Earth's, it's not actually livable by itself, but it it isn't a hellish, crushing inferno either. It may well offer advantages over Mars. Having gravity be Earth-similar is important for long term habitation. More of an atmosphere to deal with radiation without having to bore into the surface is pretty useful as well.
More to the point, you don't have to have a fragile balloon or something to keep the settlement up there. Venus is made up of a lot more CO2 by far than Earth is. Carbon Dioxide is heavier than either Nitrogen or Oxygen. Your settlement's air supply would literally be your flotation gas. The only "no fail" tech you would need, would be the same no fail tech you'd need to live on Mars. And with significant CO2, you have a much more ready supply of something that can be turned into Oxygen with scrubbers than you would on a comparatively airless Mars.
