I had a great stay at the appartement! It is confortable, very well located and very clean. The arrival was easy and so was the check out. Highlight: the sofa with great view to the avenue and the smart TV with youtube/spotify that allows you to listen to music.
I would definetely recommend it for anyone staying in Paris, because it has a great quality-price ratio.
However, some points should be made:
1- The appartement has a nice sound isolation to the street sounds, but not a good one between the floors, which means you can hear noises people make in other appartements.
During our stay, we would be disturbed everyday between 6 and 7am because of neighboors who woke up and started walking and doing their stuff, which ended up waking us up as well.
2- There is a maximum of hot water that you can use per day. So if you like to take 2 showers a day be sure to do it quickly, otherwise you'll end up with
no hot water. Be sure to not use it in the toilette sink or the kitchen, because the water system is integrated. Good way to avoid wasting water though.
