My friends and I had a nice stay at Jean Michel place.
It was very quiet even so the apartment is located directly on the street level. The beds were comfortable. (the flat is mostly for 2 couples or 2*2 friends).
The flat was very clean, and the kitchen looked quite well equipped but we didn't really use it during our stay.
The hammam was really nice.
Self check-in/out is very useful and the communication with Jean Michel went well and was nice.
Only downside: there isn't much day light in the flat
