Air conditioning in hotels/Airbnbs in Paris

I would not stay in Paris from the middle of June to the beginning of August without air conditioning and I am a person who is usually cold. You can find historical temperatures in Paris in June online but I think that it feels hotter than the reported averages. It is tougher to find apartments with air conditioning than it is to find a hotel room with it but if you use booking.com, one of the filters is air conditioning.

You shouldn't have trouble finding an air conditioned hôtel unless you're looking under three stars.
Airbnbs are a crapshoot and I don't understand the appeal when on vacation.

It can get hot in June. Especially for American standards. Last summer the first heat wave was in June

I wouldn't stay anywhere in Paris from June 1 to mid September without AC. I'm surprised you're not finding hotels with AC. Apartments are a different story. Good luck in your search!

If you stay in 3 or 4 star hotels , you can pretty much count on the availability . I stay only in 2 star hotels in Paris and will there next summer. Airb&b is not an option in Paris.

Yes, in recent years the summer months as early as beginning of June have been very hot. We were in Paris the second week of June this year. The coolest temp was 85 F, and several days reached mid-90s F. Air conditioning isn't common in France, as it is viewed as unhealthy and bad for the planet. Since Paris is a city of stone and concrete these temps can feel even hotter.

We were there in April before ac was turned on in our hotel. Temps were in the 80s and it was uncomfortably warm. I would definitely get ac in June. Use a booking site with ac as a filter. I can recommend Citadines St. Germain. Perfect location, large rooms with kitchenettes, laundry machines in the basement, and ac (just not in April!).
