Tried Searching: Various combinations of "body" "decomposure" and "smell". I ended up getting a load of lyrics for songs I'm not sure I want to hear now, and an article that mentioned a body smelling, but the closest to a time frame I got was "a long time".
So my question:
There's a body decomposing in the master bedroom of an apartment building. How long would it take before the smell would be so overwhelming that someone in another apartment, or walking along the hallway, would complain about it to the landlord? Theoretically, would someone be able to stay in the same apartment for prolonged periods of time and withstand that smell?
ETA: It would be summer, windows not opened.
