@Sandra920 you have done a great thing by coming here first to look for guidance before starting. Getting advice early can help you avoid making a lot of the mistakes new hosts make in the beginning.
(By the way: one good way to find the mistakes to avoid: go to a search engine and search for "mistakes new airbnb hosts make". You will find a whole list of articles that will be very helpful.)
Here you can ask for solutions to very specific problems, and there is a wealth of informative discussions in the archives (once you know what you look for).
Some of the good tips for new hosts:
- Make sure you are completely ready before you list. Some people start before everything is ready, but that just risks bad reviews right at the start, which is when you are most vulnerable to a bad review.
- Your photos should show your listing off in the best possible way. Spend time and trouble to make them look good. If necessary, spend money.
- If anything is confusing to you, come here and ask. The odds are that anything you encounter has been seen before by someone here.
There is, of course, a lot more to know when starting out. Read through these discussions and you will find out what problems people run into every day. Hopefully you will know how to avoid them.
Best of luck!
