Considering the increase in housing tenants (inquilinización) and financialization in Latin America, this paper explores the emergence of short-term rentals in the City of Buenos Aires, as a growing trend of housing commodification, barely incorporated into the agenda of urban studies in Latin America. To do so, we take the case of Airbnb and examined four basic dimensions to characterize the phenomenon: quantity and evolution of offers, spatial distribution, housing prices and types of owners, then comparing them with the long term rental market. Results show that short term rental shows sustained growth both over time and territory; it is a real estate market segment which is operated by concentrated and intermediary actors. Due to the low occupancy rate of the properties, the rent obtained is currently lower than in the long-term rental market. However, the post-pandemic context (still in the process of recovery) and other significant non-economic factors must be considered when interpreting these results. The paper concludes by proposing future possibilities of advance in the research of the phenomenon in Argentina. [ABSTRACT FROM AUTHOR]
