We are very sorry for what has caused you uncomfortable. for the contract that a previous guest left, the cleaning staff informed us that they forgot to put it in the place where it's supposed to be. But we will be more careful to assure such an incident will not happen again. For the man and woman that were on the rooftop, they were actually our photo-shooting staffs, who were just taking photos on the rooftop, because we want to put some rooftop photos on our Airbnb page. They did not mean to peek into your room or trying to do anything suspicious. We are very sorry that we did not expect you would see them, and may should have informed you of the photo-shooting on the rooftop. As this is not a regular photo-shooting we do, this kind of thing should not happen again, but again, we are very sorry for what caused you to feel uncomfortable. Hope for your understanding and we hope to have another chance to host you again in the future. Thank you for staying with us this time and we hope the best wishes for you.
