Let's hope they do. I spend about two months a year travelling to different countries, using mostly airbnb, but it's frustrating having to rely on host photos to see whether the apartment has a balcony or terrace -- and that's only if they think to add one. But at least I can sleep at night knowing they have shampoo. (Kidding.)
The other feature filter they should add is "waterfront" or "waterview." Booking.com has all these kinds of things listed, as a poster above noted. If I don't quickly spot a view shot on an airbnb listing, I just go there instead.
So if Airbnb staff are reading this, you're losing business.
