Me and DH have stayed in lots of Airbnb's (over 50) both in the UK and abroad - France, Belgium, Holland, Sweden and have never cleaned the house!
Of course we leave it clean and tidy as, I would hope, anyone with any decency would although have been a holiday home cleaner and a hotel room cleaner I know plenty of people are disgusting.
For us we like the fact that we can have a whole flat or even a house rather than just a hotel room. We can have a comfy sofa (or even 2) rather than having to sit on the bed in the hotel to watch tv which we both absolutely hate. We like having a kitchen and that, if we want to, we can cook for ourselves rather than having to eat out. If, for any reason, we want to just chill for a bit and read, watch tv or whatever we don't have to do it in a cramped hotel room
Whenever we have stayed in a hotel, whether a budget one or a much more expensive one, there has always been noise late at night/early morning. I am a very light sleeper and it drives me mad. People talking at the tops of their voices, slamming doors, having very noisy sex etc etc. We have never had any noise problems at any of the Airbnb's.
We have stayed in some really lovely places and almost all of them have been cheaper than a budget hotel
