We (two adults and three "children" (15, 12, 6)) had a great time in Paris staying at Sophie's appartment. Although we arrived at a rather unusual time, Sophie gave us a very warm welcome and we even found everything we needed for the breakfast the next morning waiting for us.
The appartment itself is a great place to stay, fast WiFi for the 15 years old, fun toys for the 6 years old and lots of light and character for the parents.
It is very well equipped with every household item one might need and even more important Sophie's well kept folder with good nearby restaurants and lots of other valuable information for making Paris even more enjoyable for all ages.
The location is great: You are pretty much in the middle of everything (Metro and busses nearby) and you can feel almost like a local when you walk back to the appartment in the morning with a baguette under your arm.
Sophie is a perfect host, she replied very quickly to questions in advance and offered every possible help during our stay.
We can only recommend staying there, you will love it!
