Sounds like you do the cleanup and maintenance yourself.
Most guests it takes me about 5 mins at most to turn over the room. I'd understand if I was renting the whole house out it would probably take longer. But since I live here I am going to be cleaning anyway, the guests don't really add any additional cleaning in the common areas really.
The bad to terrible guests can take anywhere from 10 mins to an hour. But that doesn't happen often at all. Plus it's usually on the lower end.
Pretty easy in general.
