Ciao @Kiara76 , you should use all the descriptive fields made available by Airbnb for the listing, in particular you should describe your apartment, for the house rules there is a special section. Include captions on your photos, too. As it is, it was difficult for me to understand what your apartment looks like. The photos can be fine as they are but they must reflect exactly what the guest will find when they arrive in your apartment. I hope I was helpful.
