Easy approach is :
Login to alfresco explorer with admin user. (http://localhost:8080/alfresco).
Go inside the space you want to hide. More Actions > Manage Space Users.
Uncheck the  "nherit Parent Space Permissions" check box.
And then verify.
For all users (except admin user), this space won't be visible.

Alternatively, in alfresco share, you can remove EVERYONE rights from Manage Permissions action of the space that you want to hide.
