1. Wifi is unstable. 2. The hotel does not have disposable brushes. 3. Bad experience about customer privacy. At 12:00 night when my whole family was resting, a stranger knocked on the room door constantly. Then the receptionist calls about I have a friend to stay with and please open the door? I don't have any friends, I'm vietnamese and I stayed there 2 nights. If more people arrive, I should be the one to inform the hotel and not in such a situation. HOWEVER, despite being disturbed by knocking on the door and continuous calls from the reception, I still have not received any explanation or apology?
