Couldn't have asked for more. I stayed in the flat for five months whilst completing an Erasmus study placement here in Paris and I was so impressed with both the flat and the hosts. Antoine was always very quick to reply to messages which was super helpful, and even assisted me to buy groceries when I first arrived as I was required to isolate for a week!
The flat itself was perfect for my stay alone - furnished with everything you could need including a washing machine, kettle, mini oven, stove tops, fridge freezer, towels, extension lead and more. The toilet flush was not working when I first arrived but Antoine kept me in the loop regarding a plumber coming to fix it, and also reimbursed me some of the rent as compensation which was very kind. Note: you have to walk up three flights of stairs to get to the flat, including one rather steep flight, but you soon get used to it.
Location is amazing - a street away from the Pantheon, metro and bus stops nearby, 10 min walk to Notre Dame, round the corner from Sainte-Genevieve (a public library), very close to the pretty Jardin du Luxembourg and it's in a great arrondissement for bars and restaurants. Ideal area for students! Only potential downside is that you can hear the bells from a nearby church every half hour but I personally quite liked that aspect.
Overall I cannot recommend enough. The flat gives you a true Parisian stay equipped with all necessities, and the hosts really are kind and generous people.
