You will have to coordinate with the host when you want to access the space.
I have the attic space above my garage available for storage. There is a ladder to get stuff up and down. Although the space is more than large enough for multiple king sized mattresses there is no way to get them up there. Perfect place to store winter/summer tires. Christmas trees and other holiday ornaments. Probably get 100 boxes of oranges up there.
