I stayed here with my family (4 people in total). The appartment was very clean and it had a lot of space (two bedrooms, two bathrooms with shower, living room (with couchbed), kitchen, dining space and a room for clothes and suitcases). The kitchen was modern and had everything you need for cooking. Washing machine and dishwasher were nice to have too. The appartment had showergel/shampoo, great bedsheets/pillows/blankets/towels. Only thing we run out of was papertowel and toilet paper.
The appartment was very hotel like: clean, nicely decorated with modern and useful furniture like many mirrors and nice good quality sofas and beds (compared to some airbnb's where I've stayed which were more like the hosts personal appartments with their personal things and furniture).
Best thing about the appartment was the location. (As a person who lives near Paris and spends a lot of time there this made me experience Paris on a whole new level!) It was right in the center with a lot of restaurants, grocery stores (franprix was almost next to it) , cafes and shops near. It was really nice to have the opportunity to walk back home on a nice lively streer after dinner instead of always taking a crowded metro. But using the metro was also easy. We mostly used Saint Paul metro stop which was about 8minute walk from the appartment. But it was very easy and quick to walk to the Seine, Notre Dame, Chatelet area and Louvre without the metro (0,5-1,5km distance maybe?). I didn't think about the location much before arriving but after our trip I dare to say that the location definitely made our trip and experience even better than expected. I definitely recommend having the location as a priority especially on short city vacations, it saves a lot of time!
The area itself was nice: a lot of people, and shops, nice buildings etc. Definitely had the "Paris vibe". Every morning we saw cleaners taking care of the streets and it was clean and well kept. Even late at night the area felt safe and wasn't loud at all (I personally didn't see any parties or clubs near.) Even though it was on a good and busy area the street wasn't loud at nights. The appartment wasn't on a main road and there wasn't many cars either, but there was a lot of tourists walking around. The appartment was on a courtyard which is behind two locked doors and the appartment itself is on a FIRST FLOOR, which was definitely a big plus! (As in Paris most appartment buildings don't have elevators so we didn't have to worry about stairs at all!) the building was nice and we didn't hear neighbors or streetlife at all.
Overall great experience! Would definitely recommend, escpecially for families. Also everytime we had a questions the hosts answered quickly! If we ever come to Paris again we would love to stay here again.
