Other than good communication and friendliness from the host, everything was bad.
First, the house was dirty. The curtains in the living room were splattered with what looked like mud and are torn in shreds. The towels in the bathroom and the sheets on the bed were stained and dirty.
Second it was super noisy. Music was blaring from a somewhere nearby from 12 noon to 3 am. You could hear it everywhere in the apartment with all windows and doors closed.
Third, the location on Airbnb is wrong. The apartment is located next to a favela and overlooks it. It's the worst possible part of Ipanema.
Last, the house is cluttered with junk. Boxes piled in the living room. The laundry area can't be entered it's so full of stuff.
