Well, not exactly to them. I would address the package to a fictional person and then leave it in the communal hallway for whomever it is in out building who opens all the parcels and disregards them if it's something boring (they don't like books) or pockets it if it's something valuable (such as a mobile phone or a delivery of sports equipment).
I have some lovely smelly past-their-best whole seabass which it would be a shame to waste...
