As Guests, we love to stay in Private Rooms when we travel... It's usually cheaper, it's great to have a local "Host", and we enjoy seeing how real people live in the towns we visit. That said, we don't really like sharing a bathroom! So when searching for a room, I usually choose to see only the "Private Room"s. But then I need to filter through those results manually to figure out which ones have a private bathroom, and which are shared. Why not have a 4th "Room Type" option: Entire Home; Private Room with Private Bath; Private Room with Shared Bath; Shared Room.
I know this idea has been mentioned several times on Host Voice already, and I've up-voted it already... to no effect. So I'm trying again.
Airbnb, please pay attention! It's an idea whose time is looooong overdue.
