I think the fact that the 3-6 months was negotiated directly with the landlord is more significant than the length of time itself. They essentially had to take their listing off Airbnb and rent it as a regular furnished apartment. This enforces a mutual sense of responsibility and respect on myself and them which is perhaps even more than would exist in a typical lease agreement, because it's done under "special circumstances". Whether you blame the hosts or the platform or the guests, that sort of respect for a place and a host just is not possible when everything is done through a giant corporate medium; and it's also not possible if it's only done for a short period of time, since there's limited accountability. 3-6 months isn't so important, but it's about where things start to be serious. Water pipes leak. Refrigerators break. You get to know people.
