The stay started off quite well. The unit is well located. The hosts were responsive and one of the owners greeted us at the apartment. To be clear, if you are staying here outside the summer, you likely will enjoy your visit. It was well laid out for our family of 4. Even with the sofa bed open, there was plenty of space in the living room.
The reason for our 1 star review is that the unit advertised portable air conditioning, and we were offered assurances, prior to arrival, that the unit was cool. It was over 90 degrees Fahrenheit in Paris when we arrived. The air conditioning units were tower fans, where water and small lunch sized ice packs could be placed inside at the base. The room became insufferably hot and humid over the course of the day. The fans were ineffective at cooling the apartment, even after swapping ice packs. We spent the night uncomfortable and profusely sweating.
We decided to leave the unit the next day due to the misrepresentation of the unit. The owner refused to refund us for the remaining unused nights of or reservation. We ultimately successfully received our money back through the AirBnB dispute process. While the owner offered to bring other fans or air conditioning units, we were not interested in troubleshooting an impromptu air conditioning solution in the apartment during very hot weather with young children. The owner will likely discredit our experience and review. Beware of staying here in the summer unless significant changes to the AC are made.
