Strange: our hosts decided to throw a large, loud party downstairs from our rental, and didn't tell us about it until 10:30 one night. There were a bunch of kids screaming in the hallway until after midnight.
They wound the party down after I told them that they were keeping us awake (once via the app, and once in person), but the situation was just weird. I paid quite a bit for a place to sleep, and the hosts made it really hard to sleep. So what were we paying for, exactly?
I've stayed in more than 50 airbnbs, and some have certainly been worse than this. It's a spacious apartment in a nice area. Not terribly clean, but not awful.
But I can't say that I've ever had hosts be this ridiculously inconsiderate. If you're going to throw a big party, don't host a family with small children -- it just isn't a nice thing to do, especially if you don't bother to let us know in advance.
