I'm currently in my company office located in the Sentier district – famous for being a startups hub. No AC, just a fan and open windows (the biggest issue is the car noise, even though traffic has been restricted for days). Lots of neighbors have AC running but all the windows and doors wide open. Edit: I live in an pre-Haussmann flat (5th floor, right under the roof). Crazy hot but no AC and no fan, all the windows open since Monday, days and night, even when I'm not at home. Crossing fingers re possible theft, but at least no one can steal my non-existent AC).
