The saved list

The heart on a space puts it on your saved list. You find it again under Saved spaces, without rebuilding the search that got you there.

Saving

The heart sits in the top right corner of every result card and on a space's own page too. One click marks it, another takes it off. The search stays where it was.

Saving is free and uses no unlock. It only needs an account, because the list belongs to the account rather than the browser. On your phone you see the same list.

Saved list or search agent

The two solve different problems, and it pays to keep them apart.

The saved list looks backwards: it holds what you have already found and do not want to lose. It does nothing on its own.

A search agent looks forwards: it describes what you are after, keeps running, and speaks up when something new matches. Creating a search agent covers it.

In practice you want both. The agent brings candidates in; the heart sorts out the ones worth thinking about.

When a space disappears

Hosts can pause or delete their listing. When that happens it drops off your saved list, because the directory no longer carries it.

That is different from a space you have already unlocked. Those stay under Unlocks, with the date and a note that they are no longer listed. So you do not lose what you paid for because somebody withdrew a listing.

A suggested order of operations

Saving costs nothing, unlocking does. So save broadly and unlock narrowly: collect a handful of candidates first, compare what the description, photos, size and price tell you, and only then unlock the two or three you actually intend to call.
