There's absolutely a school of thought which views Venus as a better colonization candidate than Mars, and as early as the 70's scientists envisioned floating cities.
In effect, a balloon full of human-breathable air would sustain itself and extra weight (such as a colony) in midair. At an altitude of 50 kilometres (31 mi) above the Venusian surface, the environment is the most Earth-like in the Solar System beyond Earth itself – a pressure of approximately 1 atm or 1000 hPa and temperatures in the 0 to 50 °C (273 to 323 K; 32 to 122 °F) range. Protection against cosmic radiation would be provided by the atmosphere above, with shielding mass equivalent to Earth's.
Humans working outside could wear simpler breathing masks rather than full pressure suits.
In fact I came here to offer a counterpoint to this statement in the article:
"Nearby Venus has far too much atmosphere, whose pressure and noxious gases would crush and choke visitors from Earth."
Of course high windspeeds and the constant bombardment of acid rain would be a problem.
I could imagine Venus one day being an exotic, cloud-top paradise for the rich (reminiscent of BioShock Infinity) that's expensive to maintain, and Mars a brute workhorse that eventually displaces it as a more resilient habitat over the very long term (eg. after terraforming).
