Perfect apartment in a perfect neighborhood.
My wife and I spent a week in Paris in July of 2022. During this time, the temperature in Paris broke all records, topping out at a blistering 41 C (106 F!). Paris apartments are generally not air conditioned, and there was great misery in Paris, particularly in top-floor apartments.
BUT! Julie's apartment has a second bedroom, located below ground level. It remained cool (and quiet, and dark) for our entire visit. Perfect sleeping.
This is important, and not just for the heat: although the little side street is reasonably quiet, the neighborhood is LIVELY. There are a many cafes with outdoor tables within a block, so the fun goes on until late. But in the lower bedroom we never heard a sound.
Speaking of the neighborhood: the apartment is close to the famed Boulevard St. Germain, and the winding streets of the neighborhoods around it, which are densely packed with cafes, restaurants, clothing stores, the (arguably) world's greatest caramel shop, etc.
Julie responds immediately to messages, and has perfect English.
I cannot recommend this apartment highly enough.
