Here are some of the things I do that have been the subject of mockery here on the forum:
I wear a headlamp and my reading glasses to make sure my 61 year old eyes aren’t going to miss something my mostly younger guests might see. I look UNDER the furniture and I vac/swiffer and periodically mop under it as well. I do allow pets and so the chance of stray tufts of hair drifting here or there make extra vigilance essential. I do charge a pet fee and I think allowing pets gives me a competitive advantage.
I use a lint roller on the linens before and after laundering. More than half the time I pick up hair that is still sticking to something after being laundered.
I periodically use a black light to look for things I’ve missed, especially after pets and male humans have stayed.
I put a new roll of toilet paper in for almost every guest. I take the partial rolls and use them in my part of the house.
Lots of people here do the following and it’s well advised that you do the same:
On a rotating basis I clean all the vent covers, wash the windows, wash the light fixtures, make sure no bugs are in the fixtures inside and out that they can get into, check the insides of drawers of dirt or hair and vacuum, take the cover off the shower drain and clean the hair out, clean the inside of any cabinet and dust off tops of shelves. Clean the baseboards, touch up paint. Dust the walls especially where it might stick near windows or vents. Dust and vac windowsills. There is always dust that seeps in and in summer usually a bug.
Once you get the routine down it doesn’t take much extra time to make sure it’s perfect. Your problem is going to be remote hosting. Good luck finding a cleaner that’s remotely (see what I did there?) close to performing at this level. To be frank I think it’s difficult to be a remote host and enter this competitive environment. Also be aware of new laws governing rentals in Miami Beach.
