I would have to agree with @Simon W.If I took over, or had a client ask me to clean their books, first thing I do is make the Balance Sheet crisp and clean.

I usually recommend clients a pretty easy cosmetic rehab which is refinish floors, replace cabinets with modern white ones, add a white stone, new appliances, new bathroom vanity/mirror/light fixture and add in unit laundry. 

We painted the outside, cleaned up the backyard, changed the fireplace, changed kitchen countertops and backsplash, added accent wallks.

Clean it up a bit to get most bang for the buck add ons and preventative damage items like water leaks.

Basically completed just needed some clean up from construction, so to be expected. 

Also Airbnb does prioritize things like looser cancellation policies, instant book, in line with market cleaning fees, etc.

If you would really like to explore the sector : why not go and message 10 to 20 operators and offer to look after their property or clean their property for a month in exchange for their knowledge and details on the numbers.

I just recently took one apart trying to get into every possible nook and cranny to clean it and it was GROSS.

Makes an amazing shot of espresso, and pretty much idiot proof so long as you have your cleaner stay on top of the cleaning and maintenance.
