@kdfrawg I'm not a fan of the stale smoke either, but standing outside doing nothing but smoke for over an hour is just out of the question, particularly in this extraordinarily windy city.
The apartment in Paris was a little easier to smoke in — the paint on the walls seemed to be less permeable. No lingering smoke smell ever. But then that did have a massive window — here, the windows barely open 10cm.
The walls here also seem to be drywall or similar – the kind you can barely wipe without smudging the texture. So I'm taking extra steps.
