Dear Dejan,
In Real estate manager

Any reservation - need approve from house owner
This will very bad if house reservation will cancel without owner.
Owner every time may edit any reservation(cancel it or change dates).
So client need only connect to property owner
If you need some other features - you may order this as "customization service" with help our contact form.
