Gregoire's place is in a fantastic location just 10 minutes walk to Notre Dame. There is one metro stop just 2 minutes from the front door and another from another line just 3 minutes in the opposite direction, giving you great metro flexibility. There is also a great patissarie just one minute from the front door. I went there for an affordable breakfast/lunch every day. The 5th floor balcony is also a very nice touch and a great place to sit if the temperature allows. On the negative side, the decoration in the room and elsewhere is spartan at best. The bed is on the floor with no frame or headboard. And there is noticeable cigarette smoke smell throughout.
