I'm sure Sam would agree that there's something a bit sterile and inhuman in reducing lived experience with another human to an evaluation to be posted on a public forum hosted by a large anonymous corporation who happened to facilitate our finding each other as tenant-landlord (which has since culminated in friend-friend), but Sam's gotta eat and you guys gotta learn why he's a great guy and that you should stay at his place so I'll comply.
Sam is at his core someone who is invested in the Human Project: that of spinning a great narrative out of the material of Authentic Life while facilitating other humans to do the same (which in contemporary times involves pointing out the snags and pitfalls and sidetracks of living under a late capitalist society that defines you by your service to Capital). While Airbnb serves as a source of income for Sam, it's apparent its place in his life is much more than that and functions, in part, as an extension of the larger Human Project. 149 George Street is not only a nice place to stay in a convenient and quaint part of Sydney that's maintained by a friendly and helpful AirBnB-hotelier; it's a place for cultural exchange, a place to have stimulating chats with other guests from all over the world and Sam, someone who has a repository of wisdom gathered from his diverse life experiences and a grand vision for how the world should be. If the convenience of the location and the amenities are not enough to convince you, come with an open mind and see what you can learn from adding yourself to the cultural mixing at 149 George Street.
