Pierres flat is at a very good location - a minute away from the metro and pretty close to the Eiffel Tower.
The room we (a couple) stayed in was very beautiful with a walk in closet and a balcony viewing the street (6th floor). Sleeping in the bed was okay, a little bit narrow but if you aren't tall it's perfect! All in all a cozy vibe.
Since Pierre wasn't home for our stay we communicated pretty clearly on, how to check-in and -out, what we are and aren't allowed to do.
I highly recommend this stay for a short trip to Paris because this flat gives you a full on French feel which puts the cherry on top :)
