Unfortunately, we arrived at the agreed upon time, 1700, to find that the apartment was occupied. After 4 hours, we were shown in to the apartment but it had been hastily prepared and it was not clean. There was food left in the microwave and fridge, the kitchen garbage was full, there was hair and dust bunnies throughout the apartment, no hand towels, only a nespresso for coffee with no pods and very limited kitchen equipment.
The person who met us with the key was friendly and helpful but it was extremely stressful as we were there during the holidays and there wasn't any other option for accommodation (hotels 98% full).
Bernadette did contact Airbnb to let them know and I received a call from them but they weren't able to secure accommodation either. Thus, we had no option but to stay in a dirty apartment.
On the positive side, it is a great location across from the RER, the beds are comfortable and the terrace is lovely. I wish it had been a better experience.
