Lovely, modern apartment but it was advertised as having air conditioning and there was only air conditioning on the lower floors. The top floor with kitchen, living room and a larger bedroom was not air conditioned. We kept the shades closed, and opened windows when we arrived back in the evenings. For some nights this was comfortable, but other nights were warmer and had less breeze and it remained very warm. Our sons did not sleep well and were uncomfortable because of the heat and the street noise from the open windows.
Also one "bedroom" was a small gym with a small portable bed (this was shown in the picture so I wasn't surprised.) What was not shown in the picture was the glass door/wall to the room; there was no privacy at all.
The apartment was very attractive and clean but uncomfortable during the hot Paris summer. The location was great and we really liked the neighborhood. This is a very nice option for 2 or 3 people, but with the additional cost per person (we are a family of 5), it was considerably more expensive than the listed rate. Considering the heat and lack of privacy, we would not rent again.
