The boxes you will access most frequently should be the last ones packed inside the storage unit. Rent a slightly or much more significant space than you need to ensure enough walking space and “sorting” space. Keep most frequently used items closer to the front and label all bins and boxes for ease.

Keeping all related things in the same public place makes for an easier search or less time spent organizing.
