The apartment we stayed in with our family of four, including an 11yo and 14yo was perfect.
It was light and airy, and though the weather very hot and the apartment on the top level, we were able to stay nice and cool.
It was also surprisingly quiet, helped by being set back off the street and we loved the free parking.
The apartment was perfectly located amidst the buzz of the Latin Quarter, allowing us to walk most places but then catch a metro very close by when necessary.
Communication with the hosts was regular, prompt and clear, which was extremely helpful.
We definitely intend to stay again next time we are in Paris!
