@Dionne1 You poor thing. What trying guests. Too hot, too cold, too hard, too soft, just like Goldilocks.
I've been very fortunate to have non-complaining, non-demanding, appreciative guests. But you know what? I think a lot of people out there are just basically unhappy these days- their life is a rat race, they don't like their jobs, they have a hard time keeping up with the bills, they've racked up huge credit card bills, they fight traffic commuting to work every day, they don't know how to deal with their back-talking kids, etc, etc. So unhappy people are discontented in general and an Airbnb host is an easy mark to take it out on.
I host sporatically, simply because there is a definite tourist season here, Early Nov- late April. My calendar is open in the summer months, except for a 1 month break I take to go up to Canada in the summer, but there just aren't many bookings then regardless. I also have friends and family show up for a few weeks here and there, so I block off my calendar and enjoy good relaxing times with loved ones in my home. So I don't find I get burned out myself, and I don't do 1 night bookings- 3's the minimum, 2 weeks the max. Also 3 day advance notice and 1 day prep time, so I'm not frantic to turn over a room.
I'd say give yourself a break from time to time, do something super nice for yourself, but I know that's hard if you're really relying on the $ to pay the mortgage and so on.
