We checked in, and immediately noticed problems with unit, in terms of Safety, Cleanliness, and general unprofessionalism.
Most important, safety. There was open, electrical wiring. An electrical power outlet was just hanging out, not attached to the wall. The smoke detectors had been removed from the unit--the mountings were there for them, but no detectors . There is a wall mounted desk that is coming away from the wall, and could fall at any time.
Regarding cleanliness, there were hairs on the sheets; stains on the couch; stains on the carpet; the walls were dirty; wet laundry (mostly towels) in a laundry basket, dirt in the cupboards where the cookware is kept.
Regarding unprofessionalism, there was no toilet paper in the bathroom.
The whole experience was disappointing, and the power outlet and the missing smoke detectors were the final straw. We called Airbnb, described the details of what was wrong with the unit, sent them photos of our concerns, and got our stay cancelled, and got a full refund. We were in the place for less than an hour.
