I am a retired Naval Officer and Desert Storm Veteran. In addition to airbnb listings in WashingtonDC and Virginia, I have vacation rental properties around the world! An internet search for Spence Witten is sure to 'find' me or my son.
On AirBnB when you selected my Private Room English Basement it was/is listed under Private Room. There are two other categories, Entire Home/Apartment or Shared Room. You did not rent an Entire Home/Apartment, you rented and received exactly what was advertised in the listing on AirBnB a Private Bedroom (in a shared Home/Apartment. I'm sorry if you did not understand the three categories that AirBnB allows for listings and you can select to choose from. You won't find an entire apartment in washington DC for the $50/night that I have this Private Bedroom listed for.
