We cancelled the stay after one night. My friend, who arrived a night before me, came to the apartment with a dead cockroach next to the bed, hair of previous guests on the floor, and some small plastic trash on the floor.
Damien was very accommodating though! Given the good cleanliness ratings, I assume our experience was a one-off experience after the cleaning staff changed. Damien was very understanding and refunded us an extra night beyond what we would have been entitled to per the refund policy.
Overall, the situation was unpleasant for us but Damien handled it very well.
