Think of this listing as part of an AirBnB hotel. You get a room in a multiple AirBnB house, and all areas are shareable with other AirBnB guests. This includes the kitchen, restroom and living room, so if previous guests have left a mess in the kitchen, then that's what will be there during your stay.
Of course, the room is exactly as listed: a bed, a desk and an AC/heating unit.
Never met Jamie or Selina, and not actually sure if they live there anyway. AirBnB hosts usually add to our visit with personal touches (notes, in-person chatting, messaging convos), but sadly, this just felt like a self-checkin hotel stay.
