I had a VERY small 2 bed apartment in college. I loved it because it was old, cheap, and very cute. There weren't any outside storage space available. Everyone who had bikes would leave them in the hallway outside their apartment door, which was pretty isolated because there were only two apartments per hall. Because my bike and my husband's bike were top of the line newly purchased road bikes, we didn't want to give anyone the apportunity to steal them. So, my husband purchased four very large J hooks at a Lowe's or Home Depot, spending only $5, and inserted them into the ceiling (making sure that they were in raftors of course) of our second room. We placed the bikes upside down with the tires hanging from the hooks. This gave us a lot of floor space to put furniture and other stuff under them.
