Storing commuter bicycle indoors during winter
Your bike would like the same conditions as you yourself would like - room temperature air and humidity.

Also bikes dislike being left salted - if your location salts the roads then rinsing this off after your ride is an excellent idea to preserve 

If space is an issue, there are several solutions for small spaces.  If you have space up high then there are rope/pulley combos that raise your bike up.   Or you can hang them vertically from the front wheel from a wall hook.  Search sites like http://instructables.com for ideas on this point.

Apartments tend to be upstairs - do be careful of your bike carrying it up stairs or manoevering it in a lift/elevator.  Carbon doesn't like being knocked or chipped, so impacts are bad.

Does your apartment have any sort of storage locker?  If there are sufficient cyclists then there may be sufficient call for a shared space which is easier to access.  Plus the rest of the building occupants won't need to put up with bikes in the hallways.
