I rent out my space while traveling. So far so good. A couple of things through research I found played a big factor into helping me out.
Makes sure your house rules include all the common sense stuff. Like get rid of your garbage, clean up after yourself if you make a mess, don't stain the towels (Mention fee if they are damaged), building staff is not available to you, quite hours, being in a building potential for noise, only put toilet paper in toilet, do not flush wipes or hygiene products, ect.
https://www.airbnbuncovered.com/ I signed up for his blog but nothing came from it, and he has some great tips.
Airbnb like to have the comforts of home so make sure you have the basics of things you have at home. Salt, pepper, cooking oil, soaps, cleaning supplies, ect.
The only issues I have had, is someone expecting a hotel stay over an airbnb (someone's place) and they didn't go over my amenity list very well. And a few stained towels, I typically note if it's the female's time of month please use dark towles and I have a dark set of sheets to use as well.
And cleaning staff, Find someone very reliable to help out and expect them to clean for the 3 hours, between guests check in and out, so charge your cleaning fee accordingly.
I do also have a 2 night min stay to help with the traffic of coming and going from my place.
If you have more questions, I am happy to help.
