What is a conventilla?

Answer 1

One possible meaning is that it could be in reference to a dictionary that may have been located on the web at www.diccionarioweb.org/d/ES-ES/conventilla. Found by using a simple Google search. But, it most likely is a Spanish originated word simply by the fact of how many Spanish based sites came back to the result of searching that word alone. However, translation services did not translate it to any possible meaning. May be a slang word.

Answer 2

A conventilla is a term used in some Latin American countries to describe a overcrowded housing situation, often found in urban slums or poor neighborhoods. It typically refers to a small, run-down building or tenement that houses multiple families or individuals in cramped conditions.
