The apartment is small and cozy as the pictures and descriptions say! However it is more than enough for 2 people, we did not have any problem with the accommodation and left quite pleased. The area is lively and it has a variety of shops, bars, cafes, restaurants, you name it. It is well connected to all the tourist hotspots, and for those with comfortable walking shoes, it's actually perfectly situated to walk anywhere in central Paris (my partner and I walked on average about 16km a day, amazing experience to see Paris on foot). Lastly, we spoke to Pascal in messages but sadly did not meet him in person, and we met Jean-François who showed us the apartment and gave us some general neighborhood tips, however I would be amiss if I did not say that it felt like he either did not have the time or could not be bothered to give us some more in depth general advice about the city itself (however we were not pushy and only conversed during check-in).
Overall, excellent experience, definitely recommended to visit.
Enjoy Paris!
