First of all, locationwise the appartement is a great choice especially with the terrace with view to the Eiffel Tower. Also, Javel is a lovely area, with small bakerys, restaurant and cafés.
The Metro and RER Station is just 5 min walking and from there you can go to Versailles directly. The way to the Eiffel Tower is a 20min walk and a pleasant one along the river.
The appartement is well equipped and offers everything you need. We were greeted by the caretaker of the house who was really friendly.
The furnisher is a bit tired, but the bed and sofa bed were clean and comfortable.
Overall we had a good time at Nicole's place.
