What unit of comparison is typically used in apartment buildings and hotels?

The unit of comparison that is most commonly used in apartment buildings and hotels is based on the number of rooms. This is because both apartments and hotel accommodations are typically evaluated and marketed according to how many individual living or sleeping spaces they offer. In the context of real estate, particularly in multifamily housing and hospitality, the term "room" encompasses not only bedrooms but also common areas where occupants live, emphasizing the usability and function of the space rather than just its physical dimensions.

Using the number of rooms allows for a straightforward comparison across different properties, aiding potential renters or buyers in assessing value, capacity, and suitability for their needs. For example, when comparing hotel rates, a traveler might look at the cost per room rather than get bogged down with square footage, making "room" a more practical metric.

While square feet can be useful for comparing overall space, and terms like "space" and "apartments" may describe the property broadly, they do not capture the essential function and appeal of these types of accommodations as effectively as the room count does. Therefore, the room is the most relevant unit of measurement in this context.
