I'm married. 2 kids, 2 dogs, and a cat. 1500sq ft house. Garage is full of powertools, no room for bikes if I'm going to be actually able to make stuff in there. 3 bikes in the living room, 2 bikes in the front room when you walk in the door, 2 bikes in our bedroom, 2 bikes in my son's room, 1 bike in my daughter's room. And a frame hanging up on a wall somewhere.
It's pretty crowded, but we manage just fine. I don't like to keep the bikes outside. Many are steel and the changes in temp lead to condensation/rust.
If you've got room in the apt., try to come up with a solution to keep 2 bikes inside.
