Although closer to Earth than Mars, Venus was never considered as a destination for astronauts due to its proximity to the sun and the consequently hellish conditions on the planet.
However, a group of NASA scientists says it may actually be easier to visit Venus than Mars, as long as astronauts do not land on the surface but hover above it.
The planet's 500 degrees Celsius surface is hot enough to melt lead and its crushing atmospheric pressure is nearly 100 times greater than on earth. But the scientists say conditions are much more Earth-like just 50 kilometers up, where the temperature is around 75 degrees Celsius, the gravity is slightly lower than on Earth, and the pressure is about the same.
According to the concept, astronauts would orbit through the atmosphere in a gondola under a 130-meter long solar-powered airship, or dirigible, filled with helium, conducting science observations and experiments. The team envisions that, one day, there could be a permanent human presence in a floating city.

Sounds great, but looking at NASA's recent trackrecord, I predict nothing will come of this. If NASA ACTUALLY followed through on JUST ONE of their visionary missions then we might actually take this seriously.

it would be all fine an dandy untill the red light comes up on the dash board and thing starts to slowly fall out of the sky!

on top of that the direction of travel vis a vis the sunward location means less propulsion power, thrust etc is needed to get more stuff to Venus.
it's solar system colonization on the cheap.
And if you can find a few sunward asteroids you could then build a Bespin like Cloud City using the broken down material to fabricate or even print a huge hollow floatation body over time.
EDIT: you know Bigelowe Areospace should do this. They just love themselves some balloons.
bigelow specializes in tough inflatables. also its easy to fall towards the sun. it's the other way that's harder. yeah you would need multiple SLSs or that new ariane they are about to build. but it would not be anything that out of proportion to soon to exist capabilities and if it was there is the possibility on on orbit construction.; either supplied from earth or ISRU. And remember there is huge 2nd or third stage fuel tanks involved . those could be used as floatation cells or habitat.

How would NASA actually get all this stuff to Venus? It seems like it would take a massive space lift effort way outside of what NASA is capable of right now to get all these supplies and stuff up there.

While a cool concept , this really doesnt get us anywhere.......
NASA has stopped being an entity that actually DOES things and now just dreams up scifi.....
We dont have the tech to do this, its all good and well to "say " things but, wheres the working to actually do it?
Thats like me saying "I propose we all start communicating through ESP"
Well thats great, but "wheres the beef?"
They cant even get humans to mars yet and sustain a habitat there for any length of time......
How bout we take it one step at a time NASA
At one time in history we said "were going to put a man on the moon" and we did it.......
its like everything stopped there.......
yeah we have a rover on Mars, but how bout we push the envelope and really start pushing our tech to explore manned missions further out into space before we start telling everyone we want to do cloud cities......
