Noisy. Have been staying with Marriott for a long time. Room, styling, comfort of bed, cleanliness etc are like typical Marriott. Just 2 things that was different. One I didn't get the room type I wanted/booked. 2 I could hear deep freq noise (like machine's hum) when sleep sideways, ear on pillow. If I sleep face up the room is quiet. Unfortunately I always sleep sideways. This leads to me not able to sleep well for this trip and since just one night there I didn't get to test out other rooms. Will not choose this property in future. First time ever encounter such problem and I do travel quite a bit.
