I don't make guests sign anything, but they do need to confirm to me in writing via the Airbnb messaging system that they have read the info. Of course, you do get some guests who lie about it and said they've read everything when they haven't.
The useful thing about it though is that it makes it much easier to respond to the random complaints, e.g.
Me: Did you sleep comfortably?
Guest: No, I was woken by traffic noise.
Me: Sorry about that. The noise from the traffic is mentioned on the listing.
Guest: Oh. Okay, but the bed is too small.
Me: It's a standard double, as mentioned on the listing.
End of conversation, end of complaints, 5 star review.
Guest: I'm really sorry, but I need to leave early. You can hear the road from the room and I'm a very light sleeper. Can you refund the rest of the stay.
Me: No, I'm sorry I can't. If it was something that wasn't mentioned on the listing, that would be different, but it quite clearly states that room is not suitable for light sleepers.
Guest: No it's not. I didn't see that.
Me: Really? That's strange. Let me show you. Here it is, and here it is again under 'things you must acknowledge'.
Guest: What? Where's that section?
Me: Under house rules.
Guest: Oh. Well, I never read the rules as I'm not a rule breaker.
Me: Mmm. But you told me you had read them. I'm really sorry, but I can't refund you. You're welcome to hang out here the rest of the day though and work from the living room which faces the garden.
Guest: Okay, thanks.
