This is a wonderful place to spend time when visiting Paris. The location is fantastic and the property itself is lovely and worth remembering.
The underground parking is VERY tight, so if you are not used to very small spaces with your car, as most North Americans are not, be aware. To compensate, the city parking along the street next to the entrance is free between 2000-0900 and we found that was a more-than-adequate compensation. Also, the elevator to the building is very small.
The hosts were excellent at communicating and I would recommend this to anyone seeking a memorably great stay in Paris.
