Tough call really, it depends on the building type. My office is in the Forester queens blvd and 75th ave, we are a fireproof building, full time staff, 18hr doorman. The K line here is across from the compactor room and next to the elevators but because this building is concrete fireproof construction i don't think the elevators matter (noise wise) and so i see that as convenient...
the compactor room is kept immaculate and has a large chute (not much gets stuck which might cause an odor) so i see this as convenient and less shared neighbor walls, rather than a negative as it might be in an older building. The soundproofing is best in fireproof buildings in my opinion.
If I knew which building you were considering in your question it would be easier to share an opinion of the nearby common spaces :)
