We stayed at Emma's place for a few days during our trip in Paris and we had a great experience. The thing that we liked the most was the location of the studio, as it is just 2' walk away from the metro station and next to a plethora of cafes, restaurants and a number of bakeries which were ideal for breakfast.
In terms of the studio itself, the space was clean and exactly as described in the listing, with all the necessary things included for a comfortable and enjoyable stay. Also Emma was a really helpful host and replied to all our questions immediately. The space was quite quiet at night, with the only downside being that it is located on the ground floor, so there was some noise from people entering the building in the middle of the night or talking just outside the flat, but it was not a big deal.
Overall the space offers a very enjoyable stay and it's highly recommended!
