The place is in a very central and excellent location, the host was excellent always asking if we needed something ... its good for 1 person, for 2 people its quite small... and we were 2 adults and a baby, I consider quite small for the amount of stuff we had to carry with a baby.
We didn't like the fact that the shower was small and had a curtain rubbing on us during the shower (at least the curtain was clean).
The kitchen is also small, but functional
The lift and stairs are you guessed it.. small.. but it's Paris not Dubai lol
