You'd be floating in a haze of CO2 and sulphuric acid garnished with hydrogen sulphide, battered by raging convective winds which would make it very hard indeed to stay at a fixed altitude - which means the outer temperature would fluctuate by 10C to 50C or so without massively powerful altitude control.
You can't just drift there as if you're in a hot air balloon eating sandwiches and enjoying the view.
Venus might not be completely impossible, but it's still one of the less hospitable destinations in the solar system.
Also, smelly because of the H2S.
