You can expect to feel like you're staying at your friends house and you're worried of making noise or using a glass because your friends dad will shout.
To be clear, we are 3 very professional and tidy people, but the owner of the air Bnb who is nice enough on the whole, and whole lives next to the kitchen, kept coming out and "checking" we hadn't used glasses and not cleared them away etc. At one time he came out and stared at 3 half drunk glasses of water (which we had not finished with). It just made us all feel a bit uncomfortable.
