My wife is a superhost on AirBnB and it's not challenging - you just have to be responsive. The challenging parts are when you have difficult guests but I also pay my head of turnover to handle those issues a la carte if needed locally, otherwise my wife handles remotely.
It would be very hard to turnover my place without using a company that has staff due to it's size. Laundry takes about 5 hours alone. You have to have multiple sets of clean laundry if you're doing it right. I have a license and pay 10% TOT tax. Other operations aren't registered, don't pay hotel like taxes and don't replace with clean sheets. I did 80k in revenue on one property alone last year and I'm buying another soon. There's a lot of opportunity but you have to buy it right, meet guest expectations, and be compliant.
