Dear marcelle,
I have just seen your listings and honestly i can give you this 2 advices :
- contact a professional photographer to post better and brighter photo of your place.
- focus also on a more detailed description of your Airbnb with all the amenities and services that you offer.
Always be attentive to what your previous guests says that have liked and unlike to give a better service to them or just put new things in the house to attract potential guests.
This Is my personal opinion of course i don t know your area and i can t know the average price but you Will see that little by little with several 5 stars reviews you Will sell at a better price your home.
Have a good day and best regards from Italy
Andrea
