Requirements: Nightlife and Celebration Stuff!
An old man. A party animal. An adventurer. A gymnast. And two newlywed couples, one with a set of twins on the way. Not the people you'd expect to have any sort of connection with each other. Yet here they reside, in a building lovingly nicknamed "Apartments"-- not "the Apartments", just "Apartments". And each has a secret.
(Note: Building does not come with sims.)
