For me I only hear great things. I never Airbnb'd in the US but literally everywhere else and I personally just had amazing experiences.
If a country doesn't seem to have good Airbnb options, booking.com can provide similar-ish experiences (kitchen + homey vibes).
And if I had kids, I think Airbnb/homestay would make even more sense to me than hotels.
Together with that, I really don't like having to "fight off" cleaners wanting to clean my room every single day. Even putting up the do not disturb sign doesn't always work.
