We used to do airbnb when we lived in the Netherlands. We had a spare room and it was a good way to make a little extra money. Our kids are now 3 and 4 1/2, but this was 6-ish months ago.
We put in our ad that it was a family home, so all the people coming knew that it was likely to be crazy at mealtimes, have toys around etc. We offered breakfast, which most of the guests took us up on. Then they went out for the rest of the day, and didn't come back until after dinner. Usually, we only saw them for an hour a day (breakfast and evening). It was really a lot less imposition than we thought it might be. There was only one guy who wanted to join us for watching tv and having a beer in the evening, and we had more than 15 visitors in the few months that we hosted people.
It's not a bit deal with kids, honestly. It's a bit self-selecting, I guess. If you clearly put that you have kids, you're not going to wind up with party people anyway.
Also, how much were you thinking of charging? If you put it at a sufficiently high price, then you're not going to get backpackers anyway.
