I myself accidentally booked the wrong room because I did not know the geographical location of Hoi An area. The next day, when I knew I could not move to the hotel because the distance was quite far from me. I proactively contacted the hotel to cancel the room and received information to contact Traveloka to cancel. However, after 1 day, the hotel charged me the full fee. The hotel is unprofessional and I hope everyone should consider before booking hotels like this.
