@Sandra4590 I have 3 grown daughters and none of them expressed any concern. Maybe they don't care about me? 🙂 Just kidding, I think they know Mom can handle things pretty well and they most definitely don't call my shots nor I theirs.
I have been a home-share host since late 2016, although I have been closed due to Covid for a year and a half, but planning to open back up soon.
I have had wonderful guests, of all ages and genders from many places all over the world- it's been a great experience and I still keep in touch with some of my past guests.
I'd strongly advise you not to use Instant Book, and market towards the type of guests who will suit you and your listing. Set a minimum stay length of 2 or 3 days, so you don't end up having to spend your life cleaning, a maximum of 2 weeks, so if you don't like the guest you won't have to put up with them for too long. Don't take long term bookings- you want guests, not roommates. And set a 1- 2 day advance notice so you don't get last minute bookings. You want a chance to check out a guest's reviews and communicate with them before deciding whether to accept them or not.
You can click on anyone's profile photo here, to go to their profile page and then click on their listings to see how they market their place- mine is still active, although dates are blocked from booking. You can read how I wrote things to get some ideas, and it has worked well for me- it has pretty much attracted just the kind of guests I like.
Go for it, Mom!
