Which word refers to an unpleasant and cramped living space?

The chosen word conveys a specific meaning associated with living conditions. A "hovel" refers to a small, unsanitary dwelling that is often cramped and uncomfortable. It is typically associated with poverty and substandard living conditions, evoking images of a dilapidated space that lacks basic amenities and is far from being a desirable residence.

In contrast, the other options describe living spaces that do not evoke the same negative imagery. A mansion suggests a large and luxurious home, while a condo and an apartment imply a more modern, structured living environment, typically associated with better living conditions. Thus, "hovel" stands out as the term that specifically indicates an unpleasant and cramped living space.
