I had a fabulous stay with Catherine! Her home was perfect. Well stocked with shampoo, soap, and towels. Her morning breakfasts were so enjoyable. Coffee, juice, croissants or crepe, jam, yogurt. Her home is conveniently near an RER and Metro stop. Easy to reach from CDG airport. Her instructions to her home was also easy. To help future renters, when you walk in the building, you must go up half a flight of stairs to get to the elevators. There are two elevators and only the left elevator will reach her floor. There's a white button/switch to turn on the hallway lights if it's dark.
The room was just right for me as a solo traveler. I came back to a made bed and a bottle of water every day. She also offered to store my luggage for a few hours on my last day so I could sightsee a bit more before moving on to my next city. Catherine always asked if I needed anything and was there to help in so many ways. She spoke to me in Spanish and was very patient with me as I have forgotten a lot of Spanish!
If you get a chance, stay with Catherine when you're in Paris and try her breakfast.
