I don't recall there being any particular unpleasant whiffs, but then the sub was in wet dock at the time. I'm sure they pass the air through charcoal filters (or similar) these days to remove odorants.No daylight, no natural air all the air recycled with oxygen added but no smells taken out.
You're right about tiny quarters. I'm not particularly claustrophobic but would find being stuck inside for days on end tedious in the extreme.
