diaper storage with pack n play?

We got a pack n play travel lite crib to use as a bassinet in our bedroom until we decide to transition baby to her crib in her own room. When I put it on my registry, I didn't really think about diaper and wipes storage in our bedroom. We live in a small 2 bedroom in Brooklyn and space is right. Any suggestions for convenient diaper storage close to the pack n play? Maybe some kind of bag attachment or something? Any advice is appreciated.
