This is a big factor. Also, when traveling as a family, it's really nice to rent a two bedroom AirBNB over a hotel, or even over two adjoining rooms in a hotel (which will nearly always be more expensive than an AirBNB). Having the living room space allows adults to stay up in the evening after the kids are in bed, and/or lets the kids get up early and watch TV/have breakfast while the parents sleep in. AirBNBs often also have a dining room space or a backyard/patio, where families can play games, hang out, or otherwise spend time together after a long day of sightseeing. If you're just renting a bedroom in someone's house, that's a little different, and it's more often price-based, although having a full kitchen to use can be nice, and you can also often find AirBNBs in neighborhoods where hotels are few and far between.
