Booked this apartment specifically because it was advertised as air-conditioned, which it is not. Host consistently delayed responding to our texts. It took 2 texts and a phone call before he came down to let us into the apt. Building and elevator are modern and he helped us move in, handed us the keys, told us to text any questions, and left. Ignored our initial text asking about AC. Texted the next day, saying there is a portable AC unit that rolls from room to room. Asked him to come and show us how it worked. No response. Tried it that night, cold air out the front, hot air out the back. Texted the problem, he answered that unit must be vented to the exterior. I am allergic to the mosquitos that bite from dusk to dawn, so have to keep the unscreened windows closed at night. Explained the problem, got a nasty reply. Finally, at 10:30 PM on night 3 of our 5-night stay, he texted he could come the following morning. Told him not to bother, since unit heated the room if windows/doors were closed. He offered to refund remaining nights if we wanted to leave. At this point, this was no longer practical, given the short amount of time and our plans for our last 2 days in Paris. See photos documenting the portable AC unit, which could not possibly cool this entire apt., the poor communication, the tiny child's bed in 2nd bedroom, the lack of closet/storage space because the host left their possessions, and the thermostat showing how hot the apt. got. Avoid.
