As @Till-and-Jutta0 indicate, it looks like stays in Columbia are restricted to 30+ days unless you meet certain criteria. I did a quick Airbnb search and internet search:
"Renting a place for less than 30 days is illegal in Colombia unless it complies with a certain set of rules. In November 2018, the Government passed Decreto 2119, which states that all short term tourist accommodations must be registered with the Registro Nacional de Turismo (RNT) to operate legally."

National Tourism Registry (RNT) Registration
Remember that registration in the RNT is a prior and mandatory requirement for service providers to start their operations. For this, you must register at the following link: National Tourism Registry - RNT. According to the Colombian Tourism Law 2068 and Decree 1836, from August 23rd of 2022, after January 1, 2022, hosts who do not have a registration number and have not included it in the profile of their ads, will not be able to share their spaces located in Colombia on digital platforms.
If you have any questions about the registration process, contact the Ministry of Commerce, Industry and Tourism (MINCIT) by completing this form and/or send your questions to info@mincit.gov.co. If you live in Medellin, you can also contact the Medellín Chamber of Commerce of Antioquia at the following telephone numbers: (604) 4449758 and 018000 41200.
