The air conditioning in our 4th floor apartment was off when we returned to it at around 5:30 pm. Despite reaching out to the hosts via mags and calls no follow up was done. We spent the entire evening trying to have it resolved to no avail and finally asked air b n b to revise our stay so we could check out the next morning. We spent the night with no air conditioning. The flat had no fans. The windows open but didn’t feel safe leaving them so. The next morning around 9:30 we were told that the ACs turn off automatically when windows are opened and would turn on when they are shut. This made no sense since windows were closed much of the evening n night. Extremely frustrating experience that wasted one of only three nights were spent in Paris. At this price point a 4star hotel on Champs Elysee is available.
