At first glance of the room, on a late-day arrival, everything seemed acceptable. Once we were settled into our room, we noticed more - thick layer of black "dust" coming out of the air conditioner vents, missing smoke detector (it was found in the hallway floor, outside the room), no screw to hold the lampshade in place (it was constantly falling), cigarette ashes in the nighstand drawer, no curtains for the windows - only cheap plastic blinds with a few sections broken or missing, no screen or drain plug in the sink, bottom of the shower curtain was covered in mildew (couldn't see until it was wet), and the tub took over 25 min to drain after a short shower.
The dirty shower in the morning was the "last straw" so to speak, so we cancelled the rest of our reservation and found a new place to stay.
