We share a corridor with one other apartment. Our neighbours kept leaving bin-bags in corridor overnight. Always very smelly bin-bags (soiled nappies, rotting food stench). The smell was coming into our apartment so we started taking their bin-bags downstairs to bin-store ourselves and they soon got the hint and stopped leaving them there.
But the last 4 days our shared corridor REEKS! The smell of dirty nappies is so strong it's seeping into our apartment. When we open our front door it's overpowering. I can't see any bin-bags around so either they've been leaving them in corridor overnight then removing them very early, or they're concealing them (they keep bits of old furniture etc outside their door so could put bin-bags out of sight) or possibly their toddler had an accident on the corridor carpet or a bag leaked (no stain that I can see but noticed a bottle of cleaning-fluid near their door).
The smell is horrendous and is making my morning sickness much worse. AIBU to think it's disgusting to contaminate a communal area in this way? How do we raise it with them without offending them, especially as there are no visible rubbish-bags anymore just the horrendous smell? I'm tempted to put a note under their door or a general notice on the front door downstairs e.g. 'for hygiene reasons please do not leave rubbish-bags in communal areas'...
