Marc and Xavier's place was very comfortable, even during a hot weekend in Paris. The air conditioner unit was much appreciated. We were able to cook dinner in the kitchen and relax in the apartment after a hot day sightseeing - and we were able to close the kitchen door to keep the cooking heat away from the rest of the apartment. My kids loved the tv with english language stations. The location is amazing; we watched the Tour Eiffel light up at night right from the balcony! I appreciated being able to make coffee in the morning while everyone else was getting ready for the day. The beds are comfortable with plenty of nice pillows. The two full bathrooms are great; there were little soaps and an all-over shampoo which was really nice (I don't like to pack soap in my luggage). There is an elevator so you don't have to take the stairs if you don't want to. It was nice and quiet in the building, and the neighborhood is pretty quiet too. My family had a great time, and we definitely recommend this place in Paris!
