Hi @Sharon211 Lovely Place.
A couple of other points I think you need to tighten up your house rules for examples.
1. Noise restrictions late at night/early hours
2. No parties or gatherings
3. Only those who have booked and paid to stay /visit
Also you have your check in anytime after noon which means they can check in at 3 .00 a.m. in the morning and you would need to be there to let them in !
Also have photos of all the facilities in the flat ie sofa bed, box room and garden.
If you don't have them look at short term lets insurance, CCTV and having a deposit for your listing.
