The storage filters
The space type is a long list, from a private storage room to a storage container or a locker. Picking several types widens the results: it is enough that the space is one of them.
What fits works the other way round. It is a list of requirements, so a space appears only if it supports everything you marked. Marking four items narrows far more than marking one.
Ground floor leaves spaces on the ground floor, and 24/7 access leaves spaces you can enter at any hour. The app also has a climate control filter.
These filters describe the space itself, not its availability. When you need it and for how many months are separate questions in the search bar.
