Hello @Mohammed312 and welcome to the community center.
This is the place full of tips! Thousands of hosts posted here for years, so there are numerous discussions on various topics. Therefore, start just by browsing this forum and read!
And ... in order not to feel that your first post is unaswered, here is one: create a hidden corner or secret place in your rental that guests can accidentally discover. Put there some gift (a box of cookies or something like this) and a note like "Congratulations, you found a secret place! We wish you a pleasant stay".
