The place is very well located 3 stations near by and close to the champs Elyse which allow you to go everywhere in Paris in arround 25 min. Be careful if you have motor skills issue as the flat is on the 5th floor with no lift and a very narrow staircase.
The host is fast to reply and willing to find a solution if there is a problem.
Overall for paris and the location is a good deal, I will just say if you are picky then go to an hotel if not this place is for you.
