Positives : Great central location. Close to the metro, opera, gallery Lafayette and louvre museum. Nicely decorated studio. Good place for 3 people. Thibault is very responsive in case you need something.
Negative: Cleanliness need to improve - overall it was ok but devil is in the details. Lift is very small and can accommodate atmost 2 people with a bag at one time. We were traveling with a kid and with baby pram was not very convenient.
Overall, if two of you without kid are traveling to Paris and need a place close to everything - then this is a great place to stay.
