Hi @Emile2
the payment normally is processed the day after the check in, and will arrive in your account maybe in 2 or 3 days from that day. but if the guest call before 24 hours and ask for a refound most probabily he will get the money back, but depends, anyway I'm not totally sure cause I never had this kind of situations, luckly.
beside that, I suggest to take better pictures of your apartment during the day time, the pics that you have now in night time are quite depressing, and remember to keep the camera in landscape orientation, not in weird angle. 🙂 if you are not sure call a professional photographer, what you will pay in photo, you will get back in booking.
you talk about a beautiful view from your apartment but I can't see from the pictures. there is the picture of your building from outside and that's ok, but actually is more important see how it is from your window or balcony, if you have one.
Keep open the curtains, give light and fresh feelings to your place.
Good luck
cheers Raf
