Yeah, I've stayed in tons of them. Only had 2 that didn't work out and I had to leave, out of probably like 50 since I joined in 2010.
One thing to be aware of is that most people are loath to leave a bad review for anyone that they've met and liked. Even me --
I stayed at a place in Crown Heights Brooklyn a few years ago, and the woman renting it was lovely and the place was cute, but there were cockroaches in the kitchen at night. I didn't mention that in my review, because I guess I felt like it wasn't her fault or something? I did leave private feedback for her but didn't feel like it was right to tank her average review for something she probably couldn't do much about in a 100 year old apartment building in Brooklyn.
Anyway, I'm not unusual -- even though you do get some crazies leaving 1-star reviews, most Airbnb reviews are pretty positively biased. So, I advise discarding anything that is not super close to 5 stars. If something is 4 stars or less, stay far, far away.
