My wife and I stayed at Jean's place for 10 nights recently with our one year old daughter. We enjoyed our stay. The place had all the amenities wee needed including a washer, full kitchen, and a bathtub. The location was central to everything including the Les Halles train station.
Jean was professional, courteous, and helpful. The only minor concerns we had was that there was some dust under the tables and curtains which our daughter got into and the sofa bed was a bit noisy. Other than that the place including the kitchen and bathroom was very clean. If we didn't have our daughter with us, we would not have noticed those things.
I would definitely recommend the place to my friends and would stay here again.
