Cute boutique hotel with accommodating staff. My wife and I stayed 3 nights during our honeymoon to explore the area around the Jardin du Luxembourg.
We did stay during some street construction occurring right in front of the hotel, which was jarring to wake up to before 7am. The front desk relocated us from first to fourth floor which helped, but with no air conditioning we had to keep the windows open in the summer to stay cool, and the street construction crews were just carelessly loud each morning.
All things considered I would recommend this hotel due to the staff's flexibility and kindness, the comfort/cleanliness of the room, and the proximity to the Jardin, Pantheon, and other nearby attractions.
