What is the difference between multi-unit and single-unit properties?

We consider a unit to be the bookable space within any property. 

Single-unit properties are any properties in which you have a single bookable unit, be it a house, a villa, or a condo. Multi-unit properties are, by nature, a little more complex. These are typically hotel, hostel, condominium, and apartment buildings, or any other space that offers multiple bookable units.
