Nathalie and Patrick's house is a lovely space - more than enough for 2 couples travelling together. The beds were comfortable and the apartment was spotlessly clean. We didn't use the kitchen much as we mainly ate out, but the tea and coffee-making facilities were perfect.
It's very close to a Metro stop so easy to get to other places in Paris. Although it's on a main road, it is very quiet and we were not disturbed by road noise at all.
Would definitely recommend for other travellers to Paris.
