We never met the owner, since she left the key under the door mat for us when we arrived, and told us to do the same when leaving.
The impression we got when entering the house was that someone with not great (to put it kindly) hygiene habits had left for the day and should be returning soon.
It quickly became obvious that the apartment had not been cleaned. Moreover, we found stale bread in the kitchen, garbage not disposed of, the fridge was dirty and filled with food (even a bowl with soup) and there was even what looked like a rotten lettuce and a rotten mango in the fridge. The bathroom was barely cleaned (for example the mirror had white stains that looked like from brushing the teeth in front of it), the shower curtain so dirty that we even bought a new one to replace it as we didn't want to shower with that one.
Also, knowing that 2 people were coming, the owner only left one set of towels.

The apartment has the potential to be nice, but it has too much furniture and there's very little space to move around, or even to put our bags, which was even made worst by the closets being completely full. Even the hooks by the entrance door were filled with the owner's coats, scarfs, hats and bags.

This would have been already bad by itself, but it was unfortunately made secondary by what we found when we explored the apartment.
It was the first time we used Airbnb and possibly the last
