@Helen3 is so right! So much has changed it would be hard to capture it all in a post. The one thing I would like to mention is that as Airbnb has gained traction, there have been many many new listings creating a lot of competition. We have found that it can help tremendously if you have something that makes your home standout amongst the others.
For example, we are based out of Florida in the USA. A 3 bedroom 2 bathroom house, even if nice and updated, will have a very hard time competing with a 3/2 that has a pool. People come here to be outside, not to stay inside of the Airbnb.
If your home doesn't have a standout feature, consider something like: A hot tub, nice game room, incredible outdoor amentities, etc. These will all have an upfront cost, but your long term gain will be well worth it.
Good luck as you get back into hosting! It's so rewarding!
Cheers,
