As I said, if I were looking for an airbnb for a family, I would be looking at different listings, e.g. complete apartments, in which case you would have your own bathroom. I'd image the per-person prices to be better than for a solo traveller in this case as well, as has been my experience in other areas. Weekly rates on Airbnb tend to be better than nightly as well (I didn't stay long enough). The point being, whether Airbnb in Barcelona is competitive with hotels depends on your needs, but at least in my case, it was, while providing better than hostel-like accommodations.
