I've looked around but have not been able to find anything definitive on how AirBnB defines these.
If we're renting our upstairs to just one party at a time, and the bathroom up there is dedicated to them throughout their stay (i.e., we stay us the one in our master bedroom), does that qualify as a private bath? Or is it shared because we're present in the house?
Shared seems to run the gamut from multi-stall/shower/sink hostel bathrooms to sharing one or more with the host to multiple parties of guests sharing a bathroom with each other (and potentially the host).
Is there an official AirBnB definition of these three qualifiers?
