If you are allocated the ground floor rooms, you better not be a light sleeper. It can get very noisy. The walls are thin. You can hear other rooms noises, water flowing sound, lift movement sound, lobby music.
Room isn't same as the photo they provide. Not a little. But very different room. Far from MRT. Bed full of hair or hairy stuff with black stuff x don't know its a dirt or what. Room moldy and smelly. Bonus. Bathroom same dirty with unknow smelly water. I check out in 10 minutes.
