Sofia's place is at walkable distance from Arc de Triomphe. I stayed there with my parents. Sofia gave us clear instructions to reach the apartment in every possible way. We could reach the place without any confusions. The apartment is at 3rd floor and there is no elevator in the building that caused a bit of problem to my parents who are bit old. The apartment looked much bigger in pictures than in reality. We felt it is too small for 4 people. Otherwise, great location and a good place to stay in Paris!
