Emeric's place was adequate and simple with the bare necessities of everything we needed for our 3 night stay in Paris. It was in a prime location which felt very safe and family friendly and had many cheap food places around.
Emeric was great communicating with us and even let us check in without him there.
We were in the middle of a heatwave though, and the room got very hot and there was no fan which would be an easy amenity to add.
As the apartment was also very tiny (even more so than the photos would suggest) there was also not really any room to put anything but it wasn't really a significant issue during our short stay.
Would recommend Emeric's place but for short-term stays in Paris.
