Real life Bespin does sound tempting. I don't see how a leak in Venus differs much from one on Mars. A leak won't immediately exhaust the air, in the worst case( neglecting explosion, and a leak is always confined with sections( as in would be in Venus ) ) you will get a few minutes to get into a suit and repair the problem. On the other hand sulfuric acid is nasty, breathing it causes long term problems. And what happens to equipment when the acid gets inside, while you are repairing, where there isn't a plastic/ceramic shield. For external repair you will definitely also require a full body specialized suit. But let's say we would have guaranteed protection against it. What do you do with 300+km/h winds? I'm sure there is turbulence and gusts that would wreck the blimp.
