I recently started renting a flat in an older building, and the flat itself is great. However, there are some “komunalne” flats in the building, in the same part (klatka) as my flat, and certain neighbours’ smells unfortunately come into my flat through the ventilation. The worst is the old couple that live directly beneath me and smoke (it must be 1000 cigarettes each per day!) with the windows closed now that it’s a bit colder. I come home from work and my bathroom smells like someone has been sitting in there smoking. Is there any hacks or tricks Polish people traditionally have to avoid this happening? I can’t dry clothes in there as they’d stink of smoke after a day of drying.
