The unit was very dirty. Bathroom vent had all sorts of dirt and dust stuck all over it, behind the sink looked grimy. The sheets, pillow cases especially, smelled like someone else's head, so we washed all the sheets. There was other people's hair on the counter in the bathroom cubbie. ALL floor corners were so incredibly dirty, all the floor boards the same. But worst of all was the air intake at the top of the stair, pitch black with stuff hanging off the metal. All air vents had black on the ceiling because the air intake filter was so dirty it was spewing black air out. I don't mind old, but this was DIRTY
