False. There is a high altitude layer (somewhere around 50 km above the surface) that is cool enough and at the right pressure, but none of it is breathable. The scifi about a floating city likely comes from the proposals that have been made to build a floating laboratory around this depth... but that still doesn't mean the atmosphere would be breathable (think of the Venusian atmosphere as an ocean, and the lab would be a submarine floating in it).
