The apartment is in an excellent location for getting around Paris, just a few short steps from transportation and great places to eat, etc.
Great neighborhood. The steps weren't as bad as I was expecting, it helped to burn a few extra calories each day to offset the Nutella Crepes.
Received 3 emails from the host before arrival asking us to keep quiet in the staircase and don't disturb the neighbors, don't make noise in the apartment, "never". We were also told that if we scratched the walls in the staircase that we would loose our deposit, etc. There was even a note on the back of the door inside the apartment with the same warning. I get it, be respectful of the other residents.
However, on our second night the neighbor below us had an all out party until 4am loud music, singing, etc. This kept our whole family awake most of the night, the floor was vibrating. I contacted the host and he replied that he has no control over the building. I guess the warnings only apply to us.
