Charles’ apartment is very well located. A few steps from Trocadéro and Eiffel Tower, close also to the Bois de Boulogne, it is very well connected with 2 major Metro lines nearby (lines 6 and 9).
The neighborhood is very convenient with all the facilities needed and the flat is large enough to accommodate a family.
At last Charles is very reactive and flexible.
I recommend a stay at his place.
