It'd "feel" like a vacuum, until you passed out. But it would mean that you wouldn't need to expend so much energy to heat your shelter, and that greenhouse-based farming is a lot easier.
The important thing to note is that there are actually places on Earth that are in some peculiar respects less habitable than Mars. Overall they're not, but in terms of specifics like temperature they are. Mars settlement is achievable, assuming we can physically get there for less than the insanely high costs NASA throws around.
The location of this town probably wouldn't be habitable (or barely so) without a lot of imported electric and fossil fuel energy.
