Extremely difficult check-in.
Overall, the stay at this place was quite nice. We liked the apartment and the location was wonderful. However, the check-in process was pretty bad. We had to walk to some store a ways away to pick up the key. When we got to the store, they couldn't unlock the box. I had to make several phone calls and no one really spoke English and my French isn't very good. It turned out that the key was with the house keeper but there was no way to reach this house keeper. We got really lucky and someone let us in (a stranger by chance) and lead us to the place. We knocked loudly until the house keeper showed up.
The trash was also not taken out and there was food in the carpet so that wasn't great either.
We were not able to reach an actual host during a whole stay and it was just some 3rd party "check-in" service.
I would highly suggest that the owner of this AirBnB use another service than "key nest" as it was rather difficult to get into our place.
