I think it would be better to put their predicament before their identity in this case.

Attempting to survive in a luxurious museum while humanity ends, seven art students find that life continues in extraordinary ways.

Apart from that it’s hella vague. Surely most light apocalyptic stories go the same way? I’m not sure you need that in. You may have some leeway if it’s a short film, though.

Hope it helps!

EDIT: I literally just noticed the comedy tag. Your logline sounds more like an apocalyptic drama.? So. If the comedy isn’t inherent in the setting (I don’t see it, anyway) where does the humor come from? Think on how to show that in the logline.
