My son, daughter and their children also rented an apartment from Jo at the same time. She is very accommodating and flexible. She met us all from the taxi, nothing was too much trouble. Once my adult children were settled into their apartments she took us round to ours.
The flats are of a very high standard. All of the pictures and facilities are exactly as they are in the flats. We had an Irish pub facing us but the flat was very quiet, the supermarket was two doors away and the RER into Paris was about 2 mins, opposite the beautiful Chateau St Germain en Laye. Lots of places to eat and drink, we were enthralled with the area. There was no down side to this trip except for my French, but most people spoke good English! :-)
