I am from Vietnam. As soon as I arrived, the receptionist said to upgrade my room package (the room I booked was a basic room) without any extra charge and took me to the room. The room was very noisy with the sound of the central air conditioner outside. I immediately asked to change the room and they changed me to a basic room. They think everyone is easy to be fooled.
Basic room: the air conditioner inside is noisy, it is difficult to sleep well at night when sleeping. The pillows smell bad, extremely bad, I asked to change for the third time but all of them had a very bad musty smell. At night when sleeping, the room will smell bad, I think there is a problem with the air conditioner's air duct
