I looked quickly; here are my thoughts:
1. I would add some color to the kitchen and bath, with inexpensive accessories like dishtowels. That is my personal preference.
2. Perhaps remove the hose and rephotograph the patio. A hose is a reminder of Work-to-do, and you want your place to look all relaxing. (It reminded me that we also need to put away our hose.)
3. Do you really not have a separate entrance to this place? That was not checked on your amenities.
4. Perhaps provide a few more amenities on the list? For example, I put in shampoo/body wash/conditioner dispensers in each bath. So I can provide it, but not bottles sitting around.
5. I hope you can get feedback from your first guest, because that is likely to be the most helpful. This looks like a nicely-done place!
